10 Troubleshooting
10.1 Set Up Your Computer’s IP Address
This section shows you how to set up your computer to receive an IP address in Windows 2000, Windows NT
and Windows XP. This is ensures that your computer can communicate with your ZyWALL.
1 In Windows XP, click Start, Control Panel.
In Windows 2000/NT, click Start, Settings, Control Panel.
2 In Windows XP, click Network Connections.
In Windows 2000/NT, click Network and Dial-up Connections.
Problem Corrective Action
None of the LEDs turn
on.
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.
Cannot access the
ZyWALL from the
LAN.
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 10.1.
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.
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.
Click WAN in the navigation panel to verify your settings.
Cannot establish a
VPN connection
Make sure the ZyWALL and the remote IPSec router use the same VPN settings. Click
VPN in the navigation panel to configure advanced settings.
Access a web site to check that you have a successful Internet connection.
