Chapter 1 Chapter 1: Introduction Introduction to the Router Thank you for choosing the Linksys 10/100 16-Port VPN Router. The Router lets multiple computers in your office share an Internet connection, and its 16 ports offer versatility. Two are dedicated Internet ports that let you connect a second Internet line as a backup, or you can use both Internet ports at the same time, allowing the Router to manage bandwidth demands for maximum efficiency. Up to five of the 13, full-duplex, 10/100 local ports can be reconfigured as Internet ports, for an up to seven-port failover or load balanced redundancy. A dedicated DMZ port gives you a publicly accessible channel so you can set up a web or FTP server. For remote connections, up to 50 remote office or traveling users can securely connect to your office network using the Router’s Virtual Private Network (VPN) capability. Use the browser-based utility to configure settings and run convenient wizards that will help you set up the Router and its access rules. Introduction to VPNs A VPN is a connection between two endpoints—a VPN Router, for instance—in different networks that allows private data to be sent securely over a shared or public network, such as the Internet. This establishes a private network that can send data securely between these two locations or networks. The private network is established by creating a “tunnel”. A VPN tunnel connects the two computers or networks and allows data to be transmitted over the Internet as if it were still within those networks. A VPN tunnel uses industry‑standard encryption and authentication techniques to secure the data sent between the two networks. Virtual Private Networking was created as a cost-effective alternative to using a private, dedicated, leased line for a private network. It can be used to create secure networks linking a central office with branch offices, telecommuters, and/or professionals on the road. There are two basic ways to create a VPN connection: VPN Router to VPN Router •• computer (using VPN client software) to VPN Router •• The VPN Router creates a “tunnel” or channel between two endpoints, so that data transmissions between them are secure. A computer with VPN client software can be one of the two endpoints. For an IPSec VPN tunnel, the VPN Router and any computer with the built-in IPSec Security Manager (Windows 2000 and XP) can create a VPN tunnel using IPSec (Windows Vista uses a similar utility). Other Windows operating systems require additional, third-party VPN client software applications that support IPSec to be installed. NOTE: The 10/100 16-Port VPN Router supports IPSec VPN client software, including the Linksys QuickVPN software. (For more information, refer to “Appendix B: Linksys QuickVPN for Windows 2000, XP, or Vista”.) For a PPTP VPN tunnel, the 10/100 16-Port VPN Router and any computer running Windows 2000 or XP can create a VPN tunnel using PPTP. VPN Examples The following are examples of a VPN tunnel between two VPN routers and a VPN tunnel between a computer using VPN client software and a VPN router. VPN Router to VPN Router For example, at home, a telecommuter uses his VPN Router for his always-on Internet connection. His Router is configured with his office’s VPN settings. When he connects to his office’s router, the two routers create a VPN tunnel, encrypting and decrypting data. As VPNs use the Internet, distance is not a factor. Using the VPN, the telecommuter now has a secure connection to the central office’s network, as if he were physically connected.

Chapter 1 Internet Central Office Home VPN Router VPN Router VPN Router to VPN Router Computer (using VPN client software) to VPN Router The following is an example of a computer-to-VPN Router VPN. In her hotel room, a traveling businesswoman connects to her Internet Service Provider (ISP). Her notebook computer has VPN client software that is configured with her office’s VPN settings. She accesses the VPN client software and connects to the VPN Router at the central office. As VPNs use the Internet, distance is not a factor. Using the VPN, the businesswoman now has a secure connection to the central office’s network, as if she were physically connected.

Chapter 3 Place the wall-mount slots over the screws and slide 5. the Router down until the screws fit snugly into the wall-mount slots. Rack-Mount Placement The Router includes two brackets and eight screws for mounting on a standard-sized, 19-inch high rack. Observe the following guidelines: Elevated Operating Ambient •• If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer. Reduced Air Flow •• Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Mechanical Loading •• Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading. Circuit Overloading •• Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern. Reliable Earthing •• Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g., use of power strips). To rack-mount the Router in any standard 19-inch rack, follow these instructions. Place the Router on a hard flat surface with the front 1. panel faced towards your front side. Attach a rack–mount bracket to one side of the Router 2. with the supplied screws and secure the bracket tightly. 1 2 3 4 5 6 7 8 9 10 11 12 13 1 2 3 4 5 6 7 10/100 16-Port VPN Router LAN/Act LAN/Act Internet/Act RV016 9 10 12 13 1 2 3 4 5 6 7 Internet Internet DMZ 11 RV016 10/100 VPN Router Attach the Brackets Repeat step 2 to attach the other bracket to the 3. opposite side.

Setup > One-to-One NAT One-to-One NAT (Network Address Translation) creates a relationship that maps valid external IP addresses to internal IP addresses hidden by NAT. A device with an internal IP address may be accessed at the corresponding external valid IP address. To create this relationship, define internal and external IP address ranges of equal length. Once the relationship is defined, the device with the first internal IP address is accessible at the first IP address in the external IP address range, and so forth. For example, you have a Local Area Network (LAN) for which the ISP has assigned the IP address range of 209.19.28.16 to 209.19.28.31, with 209.19.28.16 used as the Wide Area Network (WAN) or NAT public IP address of the Router. The address range of 192.168.168.1 to 192.168.168.255 is used for the devices on the LAN. With One-to-One NAT, the devices with the internal IP addresses of 192.168.168.2 to 192.168.168.15 may be accessed at the corresponding external IP addresses. NOTE: The Router’s WAN IP address should not be included in the range you specify.

Setup > Advanced Routing The Advanced Routing screen allows you to configure the dynamic and static routing settings. Setup > Advanced Routing Advanced Routing Dynamic Routing The Router’s dynamic routing feature can be used, so the Router will automatically adjust to physical changes in the network’s layout. Using the dynamic RIP protocol, the Router calculates the most efficient route for the network’s data packets to travel between the source and the destination, based upon the shortest paths. The RIP protocol regularly broadcasts routing information to other routers on the network. It determines the route that the network packets take based on the fewest number of hops between the source and the destination. Working Mode  Select Gateway mode if the Router is hosting your network’s connection to the Internet. Select Router mode if the Router exists on a network with other routers, including a separate network gateway that handles the Internet connection. In Router mode, any computer connected to the Router will not be able to connect to the Internet unless you have another router function as the gateway. RIP (Routing Information Protocol)  To use dynamic routing for communication of network data, select Enabled. Otherwise, keep the default, Disabled. Receive RIP versions  To use dynamic routing for reception of network data, select the protocol you want: None, RIPv1, RIPv2, or Both RIP v1 and v2. Transmit RIP versions  To use dynamic routing for transmission of network data, select the protocol you want: None, RIPv1, RIPv2 - Broadcast, or RIPv2 - Multicast.

Static Routing If the Router is connected to more than one network or there are multiple routers installed on your network, it may be necessary to set up static routes. The static routing function determines the path that data follows over your network before and after it passes through the Router. You can use static routing to allow different IP domain users to access the Internet through the Router. Static routing is a powerful feature that should be used by advanced users only. In many cases, it is better to use dynamic routing because it enables the Router to automatically adjust to physical changes in the network’s layout. NOTE: Static routing is an advanced feature. Create these routes with care. To create a static route entry, enter the following information: Destination IP  Enter the network address of the remote LAN segment. For a standard Class C IP domain, the network address is the first three fields of the Destination LAN IP, while the last field should be 0. Subnet Mask  Enter the subnet mask used on the destination LAN IP domain. For Class C IP domains, the subnet mask is 255.255.255.0. Default Gateway  Enter the IP address of the router of the network, for which this static route is created. For example, if this network is connected to the local router’s LAN port through another router, use the WAN IP address of that router. Hop Count  Enter the appropriate value (maximum is 15). This indicates the number of nodes that a data packet passes through before reaching its destination. A node is any device on the network, such as a computer or router. Interface  Select the appropriate interface. The Interface tells you whether your network is on the LAN or WAN. If the gateway router is on a LAN port, then select LAN. If you are connecting to another network through the Internet, select the appropriate WAN port option. Click Add to List, and configure as many entries as you would like, up to a maximum of 30.

DHCP > Setup The Router can be used as a DHCP (Dynamic Host Configuration Protocol) server on your network. A DHCP server automatically assigns available IP addresses to computers on your network. If you choose to enable the DHCP server option, all of the computers on your LAN must be set to obtain an IP address automatically from a DHCP server. (By default, Windows computers are set to obtain an IP automatically.) If the Router’s DHCP server function is disabled, do one of the following: Configure the IP address, subnet mask, and DNS •• settings of every computer on your network. (Make sure you do not assign the same IP address to different computers.) Set up a stand-alone DHCP server with the Router as •• the default gateway.

DHCP > Setup Setup Enable DHCP Server  To use the Router as your network’s DHCP server, select Enable DHCP Server. If you already have a DHCP server on your network, remove the check mark. Then configure the Dynamic IP settings. Dynamic IP Client Lease Time •• The Client Lease Time is the amount of time a network user will be allowed connection to the Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased” this dynamic IP address. The range is 5-43,200 minutes. The default is 1440 minutes. Dynamic IP Range Start/End •• Enter a starting IP address and ending IP address to create a range of available IP addresses. The default range is 100-149. (Make sure the Router’s LAN IP address is not in this dynamic IP range.) For example, if the Router uses the default LAN IP address, 192.168.1.1, then the starting value must be 192.168.1.2 or greater. Static IP You can assign a static IP address to a specific device based on its MAC address. Show unknown MAC addresses  Click Show unknown MAC addresses to view all devices’ IP addresses and corresponding MAC addresses. The Unknown MAC Addresses List appears. Unknown MAC Addresses List For each device, you can enter a descriptive name in the Name field. To add an IP address and MAC address set to the Static IP list, select Enable, and then click Apply. To add all IP addresses and MAC addresses to the Static IP list, click Select All. To update the on-screen information, click Refresh. To exit this screen and return to the Setup screen, click Close. Static IP Address  Enter the static IP address. You can enter 0.0.0.0 if you want the Router to assign a static IP address to the device. MAC Address  Enter the MAC address of the device. Name  Enter a descriptive name for the device. Enable  Select Enable to assign the static IP address to this device. Click Add to List, and configure as many entries as you would like, up to a maximum of 100. To delete an entry, select it and click Delete selected Entry. Block MAC address on the list with wrong IP address  To block traffic from devices with MAC addresses on the Static IP list but using the wrong IP addresses, select this option. It prevents users from changing device IP addresses without your permission. Block MAC address not on the list  To block traffic from devices using dynamic IP addresses, select this option. It blocks all devices with MAC addresses not listed on the Static IP list. DNS DNS Server 1-2  You can assign DNS server(s) to the DHCP clients so the Router will use the DNS server(s) for faster access to functioning DNS server(s). Enter the IP address of at least one DNS server. WINS WINS Server  Windows Internet Naming Service (WINS) is a service that resolves NetBIOS names to IP addresses. WINS is assigned if the computer (DHCP client) requests one. If you do not know the IP address of the WINS server, keep the default, 0.0.0.0.

NOTE: To support NetBIOS for DHCP clients, the Router uses two methods. First, when the DHCP clients receive dynamic IP addresses from the Router, it automatically includes the information of the WINS server to support NetBIOS. Second, if a user sets up a static IP address, then the IP address, subnet mask, default gateway, and DNS server settings must be configured on the Internet Protocol (TCP/IP) screen of the Windows operating system. Then the WINS IP address must be configured on the advanced TCP/IP screen. (For more information, refer to Windows Help.) Click Save Settings to save your changes, or click Cancel Changes to undo them. DHCP > Status On the Status screen, view the status information for the DHCP server and its clients. DHCP > Status Status For the DHCP server, the following information is shown: DHCP Server  This is the IP address of the DHCP server.

Click Save Settings to save your changes, or click Cancel Changes to undo them. System Management > Diagnostic The Router has two built-in tools, DNS Name Lookup and Ping, which are used for troubleshooting network problems. The Internet has a service called the Domain Name Service (DNS), which allows users to enter an easily remembered host name, such as www.linksys.com, instead of numerical TCP/IP addresses to access Internet resources. The DNS Name Lookup tool will return the numerical TCP/IP address of a host name. The ping test bounces a packet off a machine on the Internet back to the sender. This test shows if the Router is able to contact the remote host. If users on the LAN are having problems accessing services on the Internet, try pinging the DNS server or other machine at the ISP’s location. If this test is successful, try pinging devices outside the ISP. This will show if the problem lies with the ISP’s connection. Diagnostic DNS Name Lookup/Ping  Select which tool you want to use, DNS Name Lookup or Ping. Then proceed to the appropriate instructions. DNS Name Lookup Before using this tool, make sure the IP address of the DNS server is entered on the Setup > Network screen; otherwise, this tool will not work. System Management > Diagnostic > DNS Name Lookup Look up the name  Enter the host name, and click Go. (Do not add the prefix http:// or else you will get an error message.) The Router will then query the DNS server and display the results. Name  The host name is displayed. Address  The URL of the host is displayed. Ping Before using this tool make sure you know the device or host’s IP address. If you do not know it, use the Router’s DNS Name Lookup tool to find the IP address.

Click Save Settings to save your changes, or click Cancel Changes to undo them. Firewall > Access Rules Access rules evaluate network traffic to decide whether or not it is allowed to pass through the Router’s firewall. Access Rules look specifically at a data transmission’s source IP address, destination IP address, and IP protocol type, and you can apply each access rule according to a different schedule. With the use of custom rules, it is possible to disable all firewall protection or block all access to the Internet, so use extreme caution when creating or deleting access rules. The Router has the following default rules: All traffic from the LAN to the WAN is allowed. •• All traffic from the WAN to the LAN is denied. •• All traffic from the LAN to the DMZ is allowed. •• All traffic from the DMZ to the LAN is denied. •• All traffic from the WAN to the DMZ is allowed. •• All traffic from the DMZ to the WAN is allowed. •• Custom rules can be created to override the above default rules, but there are four additional default rules that will be always active and cannot be overridden by any custom rules. HTTP service from the LAN to the Router is always •• allowed. DHCP service from the LAN is always allowed. •• DNS service from the LAN is always allowed. •• Ping service from the LAN to the Router is always •• allowed. Firewall > Access Rules Access Rules Except for the default rules, all configured access rules are listed in the Access Rules table, and you can set the priority for each custom rule. If the Access Rules table has multiple pages, select a different page to view from the Jump to drop-down menu. If you want more or fewer entries listed per page, select a different number from the entries per page drop-down menu. For each access rule, the Access Rules table lists the following: Priority  The priority of the access rule is displayed, 1 indicating the highest priority. To change its priority, select a different priority from the drop-down menu. (When an access rule is created, the Router automatically assigns a priority; however, you can change the priority after the rule is created.)

Remote Security Group Type > IP Range IP range  Enter the range of IP addresses. IPSec Setup In order for any encryption to occur, the two ends of a VPN tunnel must agree on the methods of encryption, decryption, and authentication. This is done by sharing a key to the encryption code. For key management, the default mode is IKE with Preshared Key. Keying Mode  Select IKE with Preshared Key or Manual. Both ends of a VPN tunnel must use the same mode of key management. After you have selected the mode, the settings available on this screen may change, depending on the selection you have made. Follow the instructions for the mode you want to use. IKE with Preshared Key IKE is an Internet Key Exchange protocol used to negotiate key material for Security Association (SA). IKE uses the Preshared Key to authenticate the remote IKE peer. Phase 1 DH Group  Phase 1 is used to create the SA. DH (Diffie-Hellman) is a key exchange protocol used during Phase 1 of the authentication process to establish pre- shared keys. There are three groups of different prime key lengths. Group 1 is 768 bits, and Group 2 is 1,024 bits. Group 5 is 1,536 bits. If network speed is preferred, select Group 1. If network security is preferred, select Group 5.

Phase 1 Encryption  Select a method of encryption: DES (56-bit), 3DES (168-bit), AES-128 (128-bit), AES-192 (192-bit), or AES-256 (256-bit). The method determines the length of the key used to encrypt or decrypt ESP packets. AES-256 is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same encryption method. Phase 1 Authentication  Select a method of authentication, MD5 or SHA. The authentication method determines how the ESP packets are validated. MD5 is a one-way hashing algorithm that produces a 128-bit digest. SHA is a one-way hashing algorithm that produces a 160-bit digest. SHA is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same authentication method. Phase 1 SA Life Time  Configure the length of time a VPN tunnel is active in Phase 1. The default value is 28800 seconds. Perfect Forward Secrecy  If the Perfect Forward Secrecy (PFS) feature is enabled, IKE Phase 2 negotiation will generate new key material for IP traffic encryption and authentication, so hackers using brute force to break encryption keys will not be able to obtain future IPSec keys. Phase 2 DH Group  If the Perfect Forward Secrecy feature is disabled, then no new keys will be generated, so you do not need to set the Phase 2 DH Group (the key for Phase 2 will match the key in Phase 1). There are three groups of different prime key lengths. Group 1 is 768 bits, and Group 2 is 1,024 bits. Group 5 is 1,536 bits. If network speed is preferred, select Group 1. If network security is preferred, select Group 5. You do not have to use the same DH Group that you used for Phase 1. Phase 2 Encryption  Phase 2 is used to create one or more IPSec SAs, which are then used to key IPSec sessions. Select a method of encryption: NULL, DES (56-bit), 3DES (168-bit), AES-128 (128-bit), AES-192 (192-bit), or AES-256 (256-bit). It determines the length of the key used to encrypt or decrypt ESP packets. AES-256 is recommended because it is more secure. Both ends of the VPN tunnel must use the same Phase 2 Encryption setting. Phase 2 Authentication  Select a method of authentication, NULL, MD5, or SHA. The authentication method determines how the ESP packets are validated. MD5 is a one-way hashing algorithm that produces a 128-bit digest. SHA is a one-way hashing algorithm that produces a 160-bit digest. SHA is recommended because it is more secure. Both ends of the VPN tunnel must use the same Phase 2 Authentication setting. Phase 2 SA Life Time  Configure the length of time a VPN tunnel is active in Phase 2. The default is 3600 seconds. Preshared Key  This specifies the pre-shared key used to authenticate the remote IKE peer. Enter a key of keyboard and hexadecimal characters, e.g., My_@123 or 4d795f40313233. This field allows a maximum of 30 characters and/or hexadecimal values. Both ends of the VPN tunnel must use the same Preshared Key. It is strongly recommended that you change the Preshared Key periodically to maximize VPN security. Manual If you select Manual, you generate the key yourself, and no key negotiation is needed. Manual key management is used in small static environments or for troubleshooting purposes. Keying Mode > Manual Incoming and Outgoing SPI (Security Parameter Index)  SPI is carried in the ESP (Encapsulating Security Payload Protocol) header and enables the receiver and sender to select the SA, under which a packet should be processed. Hexadecimal values is acceptable, and the valid range is 100~ffffffff. Each tunnel must have a unique Incoming SPI and Outgoing SPI. No two tunnels share the same SPI. The Incoming SPI here must match the Outgoing SPI value at the other end of the tunnel, and vice versa. Encryption  Select a method of encryption, DES or 3DES. This determines the length of the key used to encrypt or decrypt ESP packets. DES is 56-bit encryption and 3DES is 168-bit encryption. 3DES is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same encryption method. Authentication  Select a method of authentication, MD5 or SHA1. The Authentication method determines how the ESP packets are validated. MD5 is a one-way hashing algorithm that produces a 128-bit digest. SHA is a one-way hashing algorithm that produces a 160-bit digest. SHA1 is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same authentication method. Encryption Key  This field specifies a key used to encrypt and decrypt IP traffic. Enter a key of hexadecimal values. If DES is selected, the Encryption Key is 16-bit, which requires 16 hexadecimal values. If you do not enter enough hexadecimal values, then the rest of the Encryption Key will be automatically completed with zeroes, so the Encryption Key will be 16-bit. If 3DES is selected, the

Encryption Key is 48-bit, which requires 40 hexadecimal values. If you do not enter enough hexadecimal values, then the rest of the Encryption Key will be automatically completed with zeroes, so the Encryption Key will be 48‑bit. Make sure both ends of the VPN tunnel use the same Encryption Key. Authentication Key  This field specifies a key used to authenticate IP traffic. Enter a key of hexadecimal values. If MD5 is selected, the Authentication Key is 32-bit, which requires 32 hexadecimal values. If you do not enter enough hexadecimal values, then the rest of the Authentication Key will be automatically completed with zeroes until it has 32 hexadecimal values. If SHA is selected, the Authentication Key is 40-bit, which requires 40 hexadecimal values. If you do not enter enough hexadecimal values, then the rest of the Authentication Key will be automatically completed with zeroes until it has 40 hexadecimal values. Make sure both ends of the VPN tunnel use the same Authentication Key. Advanced For most users, the settings on the VPN page should suffice; however, the Router provides advanced IPSec settings for advanced users using the IKE with Preshared Key mode. Click Advanced to view the Advanced settings. Advanced Aggressive Mode  There are two types of Phase 1 exchanges, Main Mode and Aggressive Mode. Aggressive Mode requires half of the main mode messages to be exchanged in Phase 1 of the SA exchange. If network security is preferred, leave the Aggressive Mode check box unchecked (Main Mode will be used). If network speed is preferred, select Aggressive Mode. If you select one of the Dynamic IP types for the Remote Security Gateway Type setting, then Main Mode will be unavailable, so Aggressive Mode will be used. Compress (Support IP Payload Compression Protocol (IP Comp))  IP Payload Compression is a protocol that reduces the size of IP datagrams. Select this option if you want the Router to propose compression when it initiates a connection. If the responders reject this proposal, then the Router will not implement compression. When the Router works as a responder, it will always accept compression, even if compression is not enabled. Keep-Alive  Keep-Alive helps maintain IPSec VPN tunnel connections. If a connection is dropped and detected, it will be re-established immediately. Select this option to use this feature. AH Hash Algorithm  The AH (Authentication Header) protocol describes the packet format and default standards for packet structure. With the use of AH as the security protocol, protection is extended forward into the IP header to verify the integrity of the entire packet by use of portions of the original IP header in the hashing process. Select this option to use this feature. Then select MD5 or SHA1. MD5 produces a 128-bit digest to authenticate packet data. SHA produces a 160-bit digest to authenticate packet data. Both sides of the tunnel should use the same algorithm. NetBIOS Broadcast  Select this option to allow NetBIOS traffic to pass through the VPN tunnel. By default, the Router blocks this traffic. NAT Traversal  Select this option to use this feature. Both the IPSec initiator and responder must support the mechanism for detecting the NAT router in the path and changing to a new port, as defined in RFC 3947. Dead Peer Detection (DPD)  When DPD is enabled, the Router will send periodic HELLO/ACK messages to check the status of the VPN tunnel (this feature can be used only when both peers or VPN devices of the VPN tunnel use the DPD mechanism). Once a dead peer has been detected, the Router will disconnect the tunnel so the connection can be re-established. Specify the interval between HELLO/ACK messages (how often you want the messages to be sent). DPD is enabled by default, and the default interval is 10 seconds.

IP Only The default is IP Only. Only the computer with a specific IP address will be able to access the tunnel. Select IP address or IP by DNS Resolved. Remote Client > IP Only IP address  Select this option if you know the static IP address of the remote computer at the other end of the tunnel, and then enter the IP address. IP by DNS Resolved  Select this option if you do not know the static IP address of the remote computer but you do know its domain name. Then enter the remote computer’s domain name on the Internet. The Router will retrieve the IP address of the remote VPN device via its public DNS records. IP + Domain Name(FQDN) Authentication The IP address and domain name ID must match the Local Gateway of the remote computer, and they can only be used for one tunnel connection. Remote Client > IP + Domain Name(FQDN) Authentication IP address  Select this option if you know the static IP address of the remote computer at the other end of the tunnel, and then enter the IP address. IP by DNS Resolved  Select this option if you do not know the static IP address of the remote computer but you do know its domain name. Then enter the remote computer’s domain name on the Internet. The Router will retrieve the IP address of the remote VPN device via its public DNS records. Domain Name  Enter the domain name as an ID (it cannot be a real domain name on the Internet). IP + E-mail Addr.(USER FQDN) Authentication Remote Client > IP + E-mail Addr.(USER FQDN) Authentication IP address  Select this option if you know the static IP address of the remote computer at the other end of the tunnel, and then enter the IP address. IP by DNS Resolved  Select this option if you do not know the static IP address of the remote computer but you do know its domain name. Then enter the remote computer’s domain name on the Internet. The Router will retrieve the IP address of the remote VPN device via its public DNS records. E-mail address  Enter the e-mail address as an ID. Dynamic IP + Domain Name(FQDN) Authentication The Local Security Gateway will be a dynamic IP address, so you do not need to enter the IP address. When the Remote Security Gateway requests to create a tunnel with the Router, the Router will work as a responder. The domain name must match the local setting of the remote computer and can only be used for one tunnel connection. Remote Client > Dynamic IP + Domain Name(FQDN) Authentication Domain Name  Enter the domain name for authentication. (Once used, you cannot use it again to create a new tunnel connection.) Dynamic IP + E-mail Addr.(USER FQDN) Authentication The Remote Security Gateway will be a dynamic IP address, so you do not need to enter the IP address. When the remote computer requests to create a tunnel with the Router, the Router will work as a responder. Remote Client > Dynamic IP + E-mail Addr.(USER FQDN) Authentication E-mail address  Enter the e-mail address for authentication. Group VPN Group No  The group number is automatically generated. (The Router supports up to two group VPNs.) Group Name  Enter a name for this group VPN, such as American Sales Group or West Coast Marketing. This allows you to identify multiple group VPNs and does not have to match the name used at the other end of the tunnel. Interface  Select the appropriate WAN port. Enable  Check this box to enable a group VPN. Local Group Setup Local Security Group Type Select the local LAN user(s) behind the Router that can use this VPN tunnel. Select the type you want to use: IP, Subnet, or IP Range. Follow the instructions for the type you want to use.

NOTE: The Local Security Group Type you select should match the Remote Security Group Type selected on the remote computer at the other end of the tunnel. After you have selected the Local Security Group Type, the settings available on this screen may change, depending on which selection you have made. IP Only the computer with a specific IP address will be able to access the tunnel. Local Security Group Type > IP IP address  Enter the appropriate IP address. The default IP is 192.168.1.0. Subnet The default is Subnet. All computers on the local subnet will be able to access the tunnel. Local Security Group Type > Subnet IP address  Enter the IP address. The default is 192.168.1.0. Subnet Mask  Enter the subnet mask. The default is 255.255.255.0. IP Range Specify a range of IP addresses within a subnet that will be able to access the tunnel. Local Security Group Type > IP Range IP range  Enter the range of IP addresses. The default is 192.168.1.0~254. Remote Client Setup Remote Client Select the type you want to use: Domain Name(FQDN), E-mail Addr.(USER FQDN), or Microsoft XP/2000 VPN Client. Follow the instructions for the type you want to use. Domain Name(FQDN) The default is Domain Name(FQDN). Remote Client > Domain Name(FQDN) Domain Name  Enter the Fully Qualified Domain Name (FQDN), which is the host name and domain name for a specific computer on the Internet. When the remote computer requests to create a tunnel with the Router, the Router will work as a responder. E-mail Address(UserFQDN) Remote Client > E-mail Address(UserFQDN) E-mail address  Enter the e-mail address of the user FQDN. Microsoft XP/2000 VPN Client Dynamic IP users, such as PPPoE or DHCP users, who use the Microsoft VPN client software, can use this option. (The Microsoft VPN client software does not support Aggressive mode and FQDN or User FQDN ID options.) Remote Client > Microsoft XP/2000 VPN Client IPSec Setup In order for any encryption to occur, the two ends of a VPN tunnel must agree on the methods of encryption, decryption, and authentication. This is done by sharing a key to the encryption code. For key management, the default mode is IKE with Preshared Key. Keying Mode  Select IKE with Preshared Key or Manual. Both ends of a VPN tunnel must use the same mode of key management. After you have selected the mode, the settings available on this screen may change, depending on the selection you have made. Follow the instructions for the mode you want to use. (Manual mode is available for VPN tunnels only, not group VPNs.) IKE with Preshared Key IKE is an Internet Key Exchange protocol used to negotiate key material for Security Association (SA). IKE uses the Preshared Key to authenticate the remote IKE peer. Phase 1 DH Group  Phase 1 is used to create the SA. DH (Diffie-Hellman) is a key exchange protocol used during Phase 1 of the authentication process to establish pre-

shared keys. There are three groups of different prime key lengths. Group 1 is 768 bits, and Group 2 is 1,024 bits. Group 5 is 1,536 bits. If network speed is preferred, select Group 1. If network security is preferred, select Group 5. Phase 1 Encryption  Select a method of encryption: DES (56-bit), 3DES (168-bit), AES-128 (128-bit), AES-192 (192-bit), or AES-256 (256-bit). The method determines the length of the key used to encrypt or decrypt ESP packets. AES-256 is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same encryption method. Phase 1 Authentication  Select a method of authentication, MD5 or SHA. The authentication method determines how the ESP packets are validated. MD5 is a one-way hashing algorithm that produces a 128-bit digest. SHA is a one-way hashing algorithm that produces a 160-bit digest. SHA is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same authentication method. Phase 1 SA Life Time  Configure the length of time a VPN tunnel is active in Phase 1. The default value is 28800 seconds. Perfect Forward Secrecy  If the Perfect Forward Secrecy (PFS) feature is enabled, IKE Phase 2 negotiation will generate new key material for IP traffic encryption and authentication, so hackers using brute force to break encryption keys will not be able to obtain future IPSec keys. Phase 2 DH Group  If the Perfect Forward Secrecy feature is disabled, then no new keys will be generated, so you do not need to set the Phase 2 DH Group (the key for Phase 2 will match the key in Phase 1). There are three groups of different prime key lengths. Group 1 is 768 bits, and Group 2 is 1,024 bits. Group 5 is 1,536 bits. If network speed is preferred, select Group 1. If network security is preferred, select Group 5. You do not have to use the same DH Group that you used for Phase 1. Phase 2 Encryption  Phase 2 is used to create one or more IPSec SAs, which are then used to key IPSec sessions. Select a method of encryption: NULL, DES (56-bit), 3DES (168-bit), AES-128 (128-bit), AES-192 (192-bit), or AES-256 (256-bit). It determines the length of the key used to encrypt or decrypt ESP packets. AES-256 is recommended because it is more secure. Both ends of the VPN tunnel must use the same Phase 2 Encryption setting. Phase 2 Authentication  Select a method of authentication, NULL, MD5, or SHA. The authentication method determines how the ESP packets are validated. MD5 is a one-way hashing algorithm that produces a 128-bit digest. SHA is a one-way hashing algorithm that produces a 160-bit digest. SHA is recommended because it is more secure. Both ends of the VPN tunnel must use the same Phase 2 Authentication setting. Phase 2 SA Life Time  Configure the length of time a VPN tunnel is active in Phase 2. The default is 3600 seconds. Preshared Key  This specifies the pre-shared key used to authenticate the remote IKE peer. Enter a key of keyboard and hexadecimal characters, e.g., My_@123 or 4d795f40313233. This field allows a maximum of 30 characters and/or hexadecimal values. Both ends of the VPN tunnel must use the same Preshared Key. It is strongly recommended that you change the Preshared Key periodically to maximize VPN security. Manual If you select Manual, you generate the key yourself, and no key negotiation is needed. Manual key management is used in small static environments or for troubleshooting purposes. Keying Mode > Manual (Tunnel Only) Incoming and Outgoing SPI (Security Parameter Index)  SPI is carried in the ESP (Encapsulating Security Payload Protocol) header and enables the receiver and sender to select the SA, under which a packet should be processed. Hexadecimal values is acceptable, and the valid range is 100~ffffffff. Each tunnel must have a unique Incoming SPI and Outgoing SPI. No two tunnels share the same SPI. The Incoming SPI here must match the Outgoing SPI value at the other end of the tunnel, and vice versa. Encryption  Select a method of encryption, DES or 3DES. This determines the length of the key used to encrypt or decrypt ESP packets. DES is 56-bit encryption and 3DES is 168-bit encryption. 3DES is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same encryption method. Authentication  Select a method of authentication, MD5 or SHA1. The Authentication method determines how the ESP packets are validated. MD5 is a one-way hashing algorithm that produces a 128-bit digest. SHA is a one-way hashing algorithm that produces a 160-bit digest. SHA1 is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same authentication method. Encryption Key  This field specifies a key used to encrypt and decrypt IP traffic. Enter a key of hexadecimal values.

If DES is selected, the Encryption Key is 16-bit, which requires 16 hexadecimal values. If you do not enter enough hexadecimal values, then the rest of the Encryption Key will be automatically completed with zeroes, so the Encryption Key will be 16-bit. If 3DES is selected, the Encryption Key is 48-bit, which requires 40 hexadecimal values. If you do not enter enough hexadecimal values, then the rest of the Encryption Key will be automatically completed with zeroes, so the Encryption Key will be 48‑bit. Make sure both ends of the VPN tunnel use the same Encryption Key. Authentication Key  This field specifies a key used to authenticate IP traffic. Enter a key of hexadecimal values. If MD5 is selected, the Authentication Key is 32-bit, which requires 32 hexadecimal values. If you do not enter enough hexadecimal values, then the rest of the Authentication Key will be automatically completed with zeroes until it has 32 hexadecimal values. If SHA is selected, the Authentication Key is 40-bit, which requires 40 hexadecimal values. If you do not enter enough hexadecimal values, then the rest of the Authentication Key will be automatically completed with zeroes until it has 40 hexadecimal values. Make sure both ends of the VPN tunnel use the same Authentication Key. Advanced For most users, the settings on the VPN page should suffice; however, the Router provides advanced IPSec settings for advanced users using the IKE with Preshared Key mode. Click Advanced to view the Advanced settings. Advanced Aggressive Mode  There are two types of Phase 1 exchanges, Main Mode and Aggressive Mode. Aggressive Mode requires half of the main mode messages to be exchanged in Phase 1 of the SA exchange. If network security is preferred, leave the Aggressive Mode check box unchecked (Main Mode will be used). If network speed is preferred, select Aggressive Mode. If you select one of the Dynamic IP types for the Remote Security Gateway Type setting, then Main Mode will be unavailable, so Aggressive Mode will be used. Compress (Support IP Payload Compression Protocol (IP Comp))  IP Payload Compression is a protocol that reduces the size of IP datagrams. Select this option if you want the Router to propose compression when it initiates a connection. If the responders reject this proposal, then the Router will not implement compression. When the Router works as a responder, it will always accept compression, even if compression is not enabled. Keep-Alive  Keep-Alive helps maintain IPSec VPN tunnel connections. If a connection is dropped and detected, it will be re-established immediately. Select this option to use this feature. AH Hash Algorithm  The AH (Authentication Header) protocol describes the packet format and default standards for packet structure. With the use of AH as the security protocol, protection is extended forward into the IP header to verify the integrity of the entire packet by use of portions of the original IP header in the hashing process. Select this option to use this feature. Then select MD5 or SHA1. MD5 produces a 128-bit digest to authenticate packet data. SHA produces a 160-bit digest to authenticate packet data. Both sides of the tunnel should use the same algorithm. NetBIOS Broadcast  Select this option to allow NetBIOS traffic to pass through the VPN tunnel. By default, the Router blocks this traffic. NAT Traversal  Select this option to use this feature. Both the IPSec initiator and responder must support the mechanism for detecting the NAT router in the path and changing to a new port, as defined in RFC 3947. Dead Peer Detection (DPD)  (This option is available for VPN tunnels only, not group VPNs.) When DPD is enabled, the Router will send periodic HELLO/ACK messages to check the status of the VPN tunnel (this feature can be used only when both peers or VPN devices of the VPN tunnel use the DPD mechanism). Once a dead peer has been detected, the Router will disconnect the tunnel so the connection can be re-established. Specify the interval between HELLO/ACK messages (how often you want the messages to be sent). DPD is enabled by default, and the default interval is 10 seconds.

10/100 16-Port VPN Router Appendix D Appendix D: IPSec NAT Traversal Overview Network Address Translation (NAT) traversal is a technique developed so that data protected by IPSec can pass through a NAT. (See NAT 1 and NAT 2 in the diagram.) Since IPSec provides integrity for the entire IP datagram, any changes to the IP addressing will invalidate the data. To resolve this issue, NAT traversal appends a new IP and UDP header to the incoming datagram, ensuring that no changes are made to the incoming datagram stream. This chapter discusses two scenarios. In the first scenario, Router A initiates IKE negotiation, while in the second scenario, Router B initiates IKE negotiation. In the second scenario, since the IKE responder is behind a NAT device, a one-to-one NAT rule is required on the NAT device. Before You Begin The following is a list of equipment you need: Two 4-Port SSL/IPSec VPN Routers (model number: •• RVL200), one of which is connected to the Internet Two 10/100 16-Port VPN Routers (model number: •• RV016), one of which is connected to the Internet Configuration of Scenario 1 In this scenario, Router A is the RVL200 Initiator, while Router B is the RVL200 Responder. 192.168.2.100 192.168.1.101 WAN: 192.168.99.22 Router B - RVL200 Responder LAN: 192.168.2.0/24 WAN: 192.168.99.11 NAT 2 - RV016 LAN: 192.168.111.1 WAN: 192.168.111.101 NAT 1 - RV016 LAN: 192.168.11.1 WAN: 192.168.11.101 Router A - RVL200 Initiator LAN: 192.168.1.0/24 Traffic in Scenario 1 NOTE: Both the IPSec initiator and responder must support the mechanism for detecting the NAT router in the path and changing to a new port, as defined in RFC 3947.

END OF SCHEDULE 1 Schedule 2 If this Linksys product contains open source software licensed under Version 2 of the “GNU General Public License” then the license terms below in this Schedule 2 will apply to that open source software. The license terms below in this Schedule 2 are from the public web site at http://www.gnu.org/copyleft/gpl.html GNU GENERAL PUBLIC LICENSE Version 2, June 1991

10/100 16-Port VPN Router Appendix J Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software—to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation’s software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author’s protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors’ reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone’s free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The “Program”, below, refers to any such program or work, and a “work based on the Program” means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term “modification”.) Each licensee is addressed as “you”. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. You may copy and distribute verbatim copies of the 1. Program’s source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. You may modify your copy or copies of the Program 2. or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: You must cause the modified files to carry a. prominent notices stating that you changed the files and the date of any change. You must cause any work that you distribute or b. publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.

10/100 16-Port VPN Router Appendix J If the modified program normally reads commands c. interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. You may copy and distribute the Program (or a 3. work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: Accompany it with the complete corresponding a. machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, Accompany it with a written offer, valid for at least b. three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, Accompany it with the information you received as c. to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. You may not copy, modify, sublicense, or distribute 4. the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. You are not required to accept this License, since you 5. have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. Each time you redistribute the Program (or any work 6. based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients’ exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.

10/100 16-Port VPN Router Appendix J If, as a consequence of a court judgment or allegation 7. of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. If the distribution and/or use of the Program is 8. restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. The Free Software Foundation may publish revised 9. and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and “any later version”, you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. If you wish to incorporate parts of the Program into 10. other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 11. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW 12. OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS END OF SCHEDULE 2 Schedule 3 If this Linksys product contains open source software licensed under Version 2.1 of the “GNU Lesser General Public License” then the license terms below in this Schedule 3

10/100 16-Port VPN Router Appendix J will apply to that open source software. The license terms below in this Schedule 3 are from the public web site at http:// .gnu.org/licenses/old-licenses/lgpl-2.1.html GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software—to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages—typically libraries—of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/ or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author’s reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the “Lesser” General Public License because it does Less to protect the user’s freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License.
