Subinterfaces
The Subinterfaces feature allows a system administrator to assign additional
IP addresses to interfaces. These are sometimes referred to as aliases or
loopback interfaces. An additional address may be assigned to the system’s
WAN interface to support, for example, another management IP address.
How Subinterfaces Works
A common use for subinterfaces is forwarding a public subnet. A subinterface
may be created to support a subnet forwarded through the Polycom V
2
IU
4350. When forwarding a subnet through the Polycom V
2
IU 4350, it is
necessary to assign an address for this subnet to the system to act as the
subnet's gateway. To configure forwarding rules, use the Forwarding Rules
submenu under the Firewall configuration link.
When applied to the WAN/Provider interface, these addresses are protected
by the same firewall policy that is applied to the WAN/Provider address.
Several other features in the system automatically create Subinterfaces. VRRP
(if supported) and Static NAT automatically create Subinterfaces.
