5.7 LAN 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).

Note: 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.
