8.5 LAN Additional Subnet
Use this
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 Zyxel Device supports multiple logical LAN interfaces via its physical Ethernet interface
with the Zyxel 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 Zyxel Device may use a LAN IP address that can be
accessed from the WAN.
