

Packets will always be untagged when they leave the Residential Gateway from its

LAN port.



When untagged packets enter the Residential Gateway from a LAN port on the

public network and leave from the WAN port of the Residential Gateway, they will be

added the PVID and P-Bit value of the incoming LAN port.



When tagged packets enter the Residential Gateway from a LAN port on the public

network and leave from the WAN port, the Residential Gateway will process them

according to their original VLAN tags. If the original VLAN tags of the tagged packets

are the same as the WAN port

’s PVID, the packets will be untagged by the

Residential Gateway. Otherwise, they will keep their original VLAN tag when they

leave the Residential Gateway.



When untagged packets enter the Residential Gateway from a LAN port on the

private network and leave from the WAN port, they will be added the PVID and P-Bit

value of the WAN interface from which they leave the Residential Gateway.



When tagged packets enter the Residential Gateway from a LAN port on the private

network and leave from the WAN port, the Residential Gateway will process the

packets according to their original VLAN tags. If their VLAN tags are the same as the

PVID of the WAN interface from which they leave, the packets will be untagged.

Otherwise, the packets will keep their original VLAN tags when they leave the

Residential Gateway.
