Chapter 56 Troubleshooting • Ping the ZyWALL from a LAN computer. Make sure your computer's Ethernet card is installed and functioning properly. Also make sure that its IP address is in the same subnet as the ZyWALL's. • In the computer, click Start, (All) Programs, Accessories and then Command Prompt. In the Command Prompt window, type "ping" followed by the ZyWALL's LAN IP address (192.168.1.1 is the default) and then press [ENTER]. The ZyWALL should reply. • If you've forgotten the ZyWALL's password, use the RESET button. Press the button in for about 5 seconds (or until the PWR LED starts to blink), then release it. It returns the ZyWALL to the factory defaults (password is 1234, LAN IP address 192.168.1.1 etc.; see your User's Guide for details). • If you've forgotten the ZyWALL's IP address, you can use the commands through the console port to check it. Connect your computer to the CONSOLE port using a console cable. Your computer should have a terminal emulation communications program (such as HyperTerminal) set to VT100 terminal emulation, no parity, 8 data bits, 1 stop bit, no flow control and 115200 bps port speed. Clicking different links in the web help displays the same help screen. This can happen with links to anchors near the bottom of an individual help file. The help screen content does not scroll down farther because the end of the help file is already displayed. This is normal and the contents to which you are linking still display. It is more noticeable with a large browser window. You can try shrinking the browser window if this is an issue. I cannot access the Internet. • Check the ZyWALL's connection to the Ethernet jack with Internet access. Make sure the Internet gateway device (such as a DSL modem) is working properly. • Check the WAN interface's status in the Dashboard. Use the installation setup wizard again and make sure that you enter the correct settings. Use the same case as provided by your ISP. I cannot update the anti-virus signatures. • Make sure your ZyWALL has the anti-virus service registered and that the license is not expired. Purchase a new license if the license is expired. • Make sure your ZyWALL is connected to the Internet. 870 ZyWALL USG 2000 User's Guide
