[Openvpn-users] only route specific traffic?

[J. Webster]

Is there a way to get the openvpn client to only route specific traffic through the VPN connection?
I know this is not the usual use of a VPN but I am using my VPN to mainly route client web traffic as a kind of pseudo proxy server but they also need access to RTMP ports.

Secondly, if I wanted to route all port 80 and 8080 traffic from the VPN through the proxy server on the server, can that be done in the server.conf or through iptables?

The client itself can't do this because packets only go to it after
being routed there.

Iptables can redirect packets based on destination ports - but expect to
be very confused if you ever need to debug the traffic with traceroute, etc.

What's the best way to monitor the traffic coming through OpenVPN?
I mean specifically web traffic ie in the same way that squid analyzes and logs all http requests.

I guess it would be easiest to just force this traffic transparently
through a squid instance on the server.
