Setting Up Your Computer’s IP Address
Skip this section if your computer is already set up to accept a dynamic IP
address. This is the default for most new computers.
The ZyWALL is already set up to assign your computer an IP address. Use this section to set up your
computer to receive an IP address or assign it a static IP address in the 192.168.1.2 to 192.168.1.254 range
with a subnet mask of 255.255.255.0. This is necessary to ensure that your computer can communicate with
your ZyWALL.
Your computer must have an Ethernet card and TCP/IP installed. TCP/IP should already be installed on
computers using Windows NT/2000/XP, Macintosh OS 7 and later operating systems.
Windows 2000/NT/XP
1. In Windows XP, click start, Control Panel. In Windows 2000/NT, click Start, Settings, Control Panel.
