Basically i have a PPTP VPN connection on my linux box (Raspberry Pi on Raspian) and I have Deluge installed with the WebUI. The client is fantastic, really love it and the functionality that comes with it but i really want to get the traffic (downloading and uploading) forced down my VPN adapter. In the WebUI under network I have tried giving the inet address listed in ifconfig, I have tried the P-T-P address from ifconfig, I have tried giving the direct vpn address, ive tried the adapter name and ive tried adding a star after the IPs but i havent have any luck.

Does any one have any idea of the quickest and easiest way of doing this? Ive tried routing as well but it was a bit unreliable...

Thank you all in advance,

You can use the owner netfilter module. For example, run deluged as a deluge user and then apply the rule:

iptables -A OUTPUT -m owner --uid-owner deluge \! -o tun0 -j REJECT

It will reject everything except connections to tun0 for any processes under deluge user.

This sounds exactly what i need thank you for such a quick response, only issues im getting now is - iptables v1.4.14: unknown option "--cmd-owner". Do you know how to resolve this? – Ash Jul 31 '13 at 13:26
@Ash I'm very sorry, seems that cmd-owner is a deprecated argument and was removed. Instead, use the uid-owner (or gid-owner) that will identify process by user/group respectively. – Igor Hatarist Jul 31 '13 at 13:37
Ahh fantastic got this set up and working now, but have a different issue now with my VPN traffic not moving :-( Thank you so much! – Ash Jul 31 '13 at 17:08
