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?
A little bit of both…
On interface Eth01 you need to prioritize the VPN packets.
On interface VPN00 you will prioritize voice packets over the data packets.
Now It seems work fine.
In the qos classifier I made a rule like that
*.* tcp Layer 7 SSLv3
Now I can made a traffic shapping on the eth01 for the vpn.
