I’have a vpn lan to lan connection between two zeroshell firewall. The vpn is over tcp protocol. In side this tunnel flows datas traffic and voip. I want to implementing a Qos for the voip traffic.
The Eth00 is the inside network, the Eth01 go outside, and Vpn00 is the lan to lan connection.
For the qos what interface I have to manage? the Eth01 or Vpn00?
