The Additional Subnet Screen - ZyXEL Communications VMG4381-B10A User Manual

8.7 The Additional Subnet Screen

Use the Additional Subnet screen to configure IP alias and public static IP.
IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The Device supports multiple logical LAN interfaces via its physical Ethernet
interface with the Device itself as the gateway for the LAN network. When you use IP alias, you can
also configure firewall rules to control access to the LAN's logical network (subnet).
If your ISP provides the Public LAN service, the Device may use an LAN IP address that can be
accessed from the WAN.
