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