Troubleshooting - ZyXEL Communications ZyWall USG 2000 User Manual

Chapter 57 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.
