7.7  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. 
Click Network Setting > Home Networking > Additional Subnet to display the screen shown
