ZyWALL USG 100/200 Series User’s Guide

• Bridge interfaces create a software connection between Ethernet or VLAN interfaces at 

the layer-2 (data link, MAC address) level. Then, you can configure the IP address and 
subnet mask of the bridge. It is also possible to configure zone-level security between the 
member interfaces in the bridge.

• Virtual interfaces increase the amount of routing information in the ZyWALL. There are 

three types: virtual Ethernet interfaces (also known as IP alias), virtual VLAN 
interfaces, and virtual bridge interfaces.

• The auxiliary interface, along with an external modem, provides an interface the 

ZyWALL can use to dial out. This interface can be used as a backup WAN interface, for 
example. The auxiliary interface controls the AUX port.

This section explains the ZyWALL’s factory default zone and interface configuration. The 
following figure uses letters to denote public IP addresses or part of a private IP address.
