8.1 Overview

The ZyWALL can act as a bridge between a switch and a wired LAN or between two routers.
This chapter describes how to configure bridge settings. This chapter is only applicable when
the ZyWALL is in bridge mode.
In bridge mode, the ZyWALL functions as a transparent firewall (also known as a bridge
firewall). The ZyWALL bridges traffic traveling between the ZyWALL's interfaces and still
filters and inspects packets. You do not need to change the configuration of your existing
network.
In the first figure below the ZyWALL is in bridge mode and is bridging traffic on the WAN.
The router device has a public WAN IP address and the ZyWALL is transparent. In the second
figure the ZyWALL is in router mode and has a public WAN IP address and routes traffic
between the LAN and WAN.
