Windows 2000: Double-click the Network and Dial-up Connections icon, then double-click the Local Area Connection icon. Click Properties on the Local Area Connection Status window and then select Internet Protocol (TCP/IP) from the list of components shown on the General tab of the Local Area Connection Properties win- dow. Click the General tab on the Internet Protocol (TCP/IP) Properties window. • If Obtain an IP address automatically (Windows 95, 98, 2000) or Obtain an IP address from a DHCP server (Windows NT) is selected, your computer has a dynamic IP address. • If Specify an IP address is selected, your computer has a static IP address. • Click Cancel to exit the window, and then click Cancel again on the remaining windows until you get back to the Control Panel. Where To Go from here… If you are set up for dynamic IP addressing, proceed to the next section, Configure the Gateway. If you are set up for static IP addressing, record your settings. You will need them for your final setup. Then set up dynamic addressing so you can continue with the configuration of the OfficeConnect Gateway. Once the unit is connected, the Power LED illuminates (green) on the front panel of the OfficeConnect Gateway Data unit. Wait for the Alert LED on the front panel to stop flashing (amber) and transition to off, within 1-2 minutes. When the Power LED is green and the Alert LED is off, it indi- cates that the OfficeConnect Gateway Data unit has successfully powered up, performed a Power On Self-Test (POST) and is now operational. 4 Operational Status Optimizing Your Computer DHCP: (Dynamic Host Configuration Protocol): Dynamic IP addressing is the type of addressing scheme most often used by Internet Service Providers (ISPs), and is also the type that is preva- lent in many existing corporate networks. The OfficeConnect Gateway, which can act as a DHCP server, is optimized for use with dynamic, rather than static, IP addressing. For most users, it is most likely that your computer or computers are already set up for dynamic IP addressing. By default, the OfficeConnect Gateway assigns IP addresses dynamically to each attached computer. Static IP Settings: IP: ___ . ___ . ___ . ___ Mask: ___ . ___ . ___ . ___ GW: ___ . ___ . ___ . ___ DNS1: ___ . ___ . ___ . ___ DNS2: ___ . ___ . ___ . ___

Wide Area Network (WAN) interface settings for your OfficeConnect Gateway or re-configure them after resetting the unit to its factory default settings. Using a web browser on your PC, launch the OfficeConnect Gateway home page by entering the OfficeConnect Gateway’s default IP address, 192.168.1.1. If after the initial connection the OfficeConnect Gateway home page (Fig 3) is displayed, then the WAN interface has already been configured for you. Congratulations, your OfficeConnect Gateway is successfully configured and ready for use. If the WAN Interface Inactive message is displayed (Fig 4), your first step is to create a password protected admin account and configure the WAN interface. Click Continue to proceed. The system will display the Username and Password Required window (Fig 5) and prompts for Username and Password. (Note: The User Name and Password entries are case-sensitive.) The default value for the User Name is admin. There is no default Password value. Enter admin in the User Name field and leave the Password field blank (no entry). Click OK. The system will display the Unprotected User window (Fig 6). You need to assign a Password for your User Name (admin). This window is displayed when the OfficeConnect Gateway Web Configurator is accessed using the system’s default password; such as during the initial config- uration of the unit or after the factory default settings have been restored. Click Apply and the WAN Interface Configuration screen will appear. Continue on to the WAN Configuration section on page 6. Configure the Gateway 5 Figure 3 Figure 4 Figure 5 Figure 6
