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.
