(virtual VLAN interface)
(virtual bridge

trunk
* - You cannot set up a PPP interface, virtual Ethernet interface or virtual VLAN interface if the underlying
interface is a member of a bridge. You also cannot add an Ethernet interface or VLAN interface to a
bridge if the member interface has a virtual interface or PPP interface on top of it.

11.2 Port Role

To access this screen, click Configuration > Network > Interface > Port Role.
Use the Port Role screen to set the ZyWALL's flexible ports as part of the lan1,
lan2 or dmz interfaces. This creates a hardware connection between the physical
ports at the layer-2 (data link, MAC address) level. This provides wire-speed
throughput but no security.
Note the following if you are configuring from a computer connected to a lan1,
lan2 or dmz port and change the port's role:
