Chapter 2 How to Set Up Your Network

ZyWALL USG 20-2000 User’s Guide

•The wan1 interface uses a static IP address of 1.2.3.4.

•Add P5 (lan2) to the DMZ interface (Note: In USG 20/20W, use P4 (lan2) instead of P5 in this

example). The DMZ interface is used for a protected local network. It uses IP address

192.168.3.1 and serves as a DHCP server by default.

• You want to be able to apply specific security settings for the VPN tunnel created by the Quick

Setup - VPN Setup wizard (named WIZ_VPN). So you create a new zone and add WIZ_VPN

to it.
