routing

So, I want to route certain traffic via a VPN connection and the rest via my normal Internet connection. I want to run several different programs and most of them don't support binding to a specific network interface (tun0 in my case).

I've managed to send a specific user's traffic via the VPN following the answers given here: iptables - Target to route packet to specific interface?

But unfortunately, when I run a server that connects to the Internet and has a web interface running on a local IP (127.0.0.1/192.168.0.*), all the Internet traffic correctly goes via tun0, but I'm unable to connect to the web interface from a local IP as a different user.

When I log in as the VPN-ified user, I can access services running on local IPs, but other users/machines can't access any servers I start.

Can anyone point me in the right direction?

Hi all, I'm setting up port forwarding for an L2TP VPN connection to the local Windows 2003 VPN server. The router is a simpel Debian machine with iptables. The VPN server works perfect.
