If you can list what you want to be routed through VPN, then
iptables can match and advanced routing rules (iproute2) can route it.
Certainly, tough, it wont be a trivial setup. But it's completly
I cant imagine how to get this advanced routing needs to work
directly on Win2k/XP/Vista .... the linux box in front of the network
is a great idea and will make this advances setups possible.
Anyway ..... usually people uses VPNs for working on some remote
site. I had some situations in which i had to through the default
gateway over the VPN. When VPN was established, normal internet traffic
wasnt allowed by my firewall on the other side. Surfing was allowed,
email was allowed, all needed traffic for WORKING was allowed. And when
people need to stop working and wanna some non-working internet
traffic, just like your World of Warcraft example, or P2p or anything
non-importante-else, they simply disconnect the VPN and there it goes,
they have their normal internet access.
I dont know your scenario, but maybe if you're thinking on setting
a front-linux-box for 1-2 machines, maybe the approach of disconnecting
the VPN and reconnecting again when needed is interesting as well. Not
the smartest way, but certainly the cheapest and most simple way.

[Openvpn-users] How to route only SOME traffic through a PPTP
Im not an
iptables expert, but I'm 99% sure that iptables in linux can do this.
So what you want is
routing based on the port number, right ?
Routing based on IP
address is not enough ? (because this is trivial to do)
