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.
