Corrective Action
Check the cable connection between the ZyWALL and your
computer or switch. Refer to section for details.
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.
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 port's status in the Status screen. Use the
installation setup wizard again and make sure that you enter the
correct settings.
