6.6 LAN IP Alias
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.
