The Network > SwitchPorts page allows you to manage the assignments of ports to
PortShield interfaces.
Overview
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.
Working in Static Mode
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.
Note 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.
Working in Transparent Mode
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.
Note Make sure the IP address you assign to the PortShield interface is within the WAN
subnetwork.
