7.5 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 PMG2006-T20A supports multiple logical LAN interfaces via its physical Ethernet interface
with the PMG2006-T20A 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 PMG2006-T20A may use an LAN IP address that can be
accessed from the WAN.
