8.5 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 GPON Device supports multiple logical LAN interfaces via its physical
Ethernet interface with the GPON 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 GPON Device may use an LAN IP address that can
be accessed from the WAN.
