ZyWALL 2 Plus User’s Guide

The following table describes the labels in this screen.

IP alias allows you to partition a physical network into different logical networks over the 
same Ethernet interface. 
The ZyWALL has a single LAN interface. Even though more than one of ports 1~4 may be in 
the LAN port role, they are all still part of a single physical Ethernet interface and all use the 
same IP address.
The ZyWALL supports three logical LAN interfaces via its single physical LAN Ethernet 
interface. The ZyWALL itself is the gateway for each of the logical LAN networks.
When you use IP alias, you can also configure firewall rules to control access between the 
LAN's logical networks (subnets).

"

Make sure that the subnets of the logical networks do not overlap.

The following figure shows a LAN divided into subnets A, B, and C.
