Retag the Packets for Identification

Packets coming from LAN IP can be retagged through QoS setting. When the packets sent out

through WAN interface, all of them will be tagged with certain header and that will be easily

to be identified by server on ISP.

For example, in the following illustration, the VoIP packets in LAN go into Vigor router

without any header. However, when they go forward to the Server on ISP through Vigor

router, all of the packets are tagged with AF (configured in Bandwidth >>QoS>>Class)

automatically.
