The Network > PortShield Groups page allows you to manage the assignments of ports to 
PortShield interfaces.

A PortShield interface is a virtual interface with a set of ports assigned to it. There are two IP 
assignment methods you can deploy to create PortShield interfaces. They are Static and 
Transparent modes. The following two sections describe each.

When you create a PortShield interface in Static Mode, you manually create an explicit address 
to be applied to the PortShield interface. All ports mapped to the interface are identified by this 
address. Static mode is available on interfaces assigned to Trusted, Public, or Wireless zones.

When you create a PortShield interface in Static Mode, make sure the IP address you assign 
to the interface is not already in use by another PortShield interface.

Transparent Mode addressing allows for the WAN subnetwork to be shared by the current 
interface using Address Object assignments. The interface’s IP address is the same as the 
WAN interface IP address. Transparent mode is available on interfaces assigned to Trusted 
and Public Zones.
