Chapter 22 LAN Setup

IP alias allows you to partition a physical network into different logical networks over the 
same Ethernet interface. The ZyXEL device supports three logical LAN interfaces via its 
single physical Ethernet interface with the ZyXEL device itself as the gateway for each LAN 
network.
