ZyWALL USG 1000 User’s Guide

This section introduces the ZyWALL’s default zone member physical interfaces and 
the default configuration of those interfaces. The following figure uses letters to 
denote public IP addresses or part of a private IP address.

Figure 63   Default Network Topology   

• The LAN zone contains the ge1 interface. The LAN zone is a protected zone. The 

ge1 interface uses 192.168.1.1.

• The WAN zone contains the ge2 and ge3 interfaces (physical ports 2 and 3). 

They use public IP addresses to connect to the Internet.

• The DMZ zone contains the ge4 and ge5 interfaces (physical ports 4 and 5). 

The DMZ zone has servers that are available to the public. These interface uses 

private IP addresses 192.168.2.1 and 192.168.3.1.
