Craig,
No, right now OpenVPN (and I believe the Linux TUN driver as well) has no
special handling for QoS such as TOS pass through between different
encapsulation layers (though it's an interesting idea).
You could, of course, apply QoS rules to OpenVPN's UDP connection or make use
of OpenVPN'
Hi there,
I use QoS routing and it works great except over openvpn/tun device.
Correct me if I am wrong but I think this is because the packets are
encapsulated within a UDP packet with no regard to what the original
packets TOS field was, so once it reaches a "real" device it is just
treat
