The configuration dialog allows you to configure to add custom virtual local area network (VLAN) tags to all traffic to a given interface.
You can use this method to create "virtual interfaces" that allow you to put several logical network zones on one physical interface. When you associate a VLAN tag with a network interface, the tag is added to all outgoing packets that are sent through this virtual interface and stripped from the incoming packets that are received on this VLAN. You can associate several VLANs with each network interface. Packets with different tags can be processed and associated with the corresponding interface.
You can find more information regarding VLAN interfaces in the following sections.
