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

You must use menu 3.2 to configure the first network. Move the cursor to the Edit IP Alias 
field, press [SPACE BAR] to choose Yes and press [ENTER] to configure the second and 
third network.

Press [ENTER] to open Menu 3.2.1 - IP Alias Setup, as shown next.
