7.5 The IP Alias Screen
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.
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.
