VLAN forwarding

VLAN forwarding allows you to forward all VLANs traffic of a trunk that was connecting two network devices and where the FortiGate has been introduced, without having to perform any further configuration.

It is recommended to configure forwarding domains for each VLAN and disable this parameter in order to avoid packet from looping into the trunk from one VLAN to another. By default, the parameter vlanforward is disabled on each physical interface of a FortiGate or VDOM in transparent mode.
