The following table describes the labels in this screen.
6.9 LAN IP Alias
IP alias allows you to partition a physical network into different logical networks over the
same Ethernet interface.
The ZyWALL has a single LAN interface. Even though more than one of ports 1~4 may be in
the LAN port role, they are all still part of a single physical Ethernet interface and all use the
same IP address.
The ZyWALL supports three logical LAN interfaces via its single physical LAN Ethernet
interface. The ZyWALL itself is the gateway for each of the logical LAN networks.
When you use IP alias, you can also configure firewall rules to control access between the
LAN's logical networks (subnets).
"
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.
