Troubleshooting - ZyXEL Communications ZYWALL 5 Quick Start Manual

For example, the "test" VPN rule allows
secure access to an web server on a
remote corporate LAN. Enter the server's
IP address (10.0.0.23 in this example) as
your browser's URL. The ZyWALL
automatically builds the VPN tunnel when
you attempt to use it.
Click SECURITY > VPN in the navigation
panel and then the SA Monitor tab to
display a list of connected VPN tunnels
(the "test" VPN tunnel is up here).

9 Troubleshooting

Problem
None of the LEDs turn
on.
Cannot access the
ZyWALL from the
LAN.
Cannot access the
Internet.
Corrective Action
Make sure that you have the power adaptor connected to the ZyWALL and plugged in to
an appropriate power source. Check all cable connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you
should contact your local vendor.
Check the cable connection between the ZyWALL and your computer or hub. Refer to
Section 1 for details.
Ping the ZyWALL from a LAN computer. Make sure your computer's Ethernet card is
installed and functioning properly.
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.
Otherwise, refer to Section
If you've forgotten the ZyWALL's password, use the RESET button. Press the button in
for about 10 seconds (or until the SYS 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 LAN or WAN IP address, you can check the IP address
in the SMT via the console port. 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 9600 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.
Click WAN in the navigation panel to verify your settings.
