View-only filed that shows the VID
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 a LAN port is allocated to the public network, you can specify its VLAN ID in
the text box and select its P-Bit value in the pull-down menu. But when a LAN port is
allocated to the private network, its VLAN ID and P-Bit value cannot be changed.
