You must define shaping on the openvpn interface if you want to prioritize
the traffic going through that interface. And you probably also want to give
the open VPN traffic itself (usually UDP 1194) a boost on the external
interface.

I have tried the following for some test until Glenn and I try passing
Tos bit through openvpn with the passtos directive which seems to be
supported now with openvpn. In my case here there is traffic from
10.19.227.18 which is a pbs phone box with h323 udp traffic for voip
and Remote Desktop 3389 no other traffic but these two above.
When you state "And you probably also want to give the open VPN
traffic itself (usually UDP 1194) a boost on the external interface."
Would the two rules work below
2:11 10.19.227.18 0.0.0.0/0 ALL
3:11 10.19.227.18 0.0.0.0/0 ALL
Then I am thinking the remote desktop protocall
will fall into the default class?
