you could do something like :

YOUR ARCH BOX ::

Then everything at your dorm that is using the arch box for a gateway will then get routed over the vpn. Is that what ya want? As long as you get the arch box vpn client going the above should work.

on your arch box ( I posted this and now its gone ) :

iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE
iptables -A FORWARD -i tap0 -o eth0 -m state –state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i eth0 -o tun0 -j ACCEPT


Any traffic you have coming in on eth0 would be sent out over the VPN. Make since?

Thanks a lot man, it's working great now. I've got my connection running though a router so that we can get on the unproxied wifi also. It's sweet.
