Configuring IP Alias

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.
When you use IP alias, you can also configure firewall rules to control access between the LAN's logical
networks (subnets).
The following figure shows a LAN divided into subnets A, B, and C.

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