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.

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

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 

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 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.
