Need a sophisicated VPN client for Ubuntu 9.04

Question

I use the builtin VPN configuration of NetworkManager to connect to our PPTP VPN server. Actually it is a barebone VPN configuration which routes all your traffic through VPN. I'm looking for a sophisicated VPN client which is configurable and will be able to route traffic from certain sources or applications through the VPN and others through the default network. For example, our custom app traffic will route through VPN and others not.

Cross posted here in Serverfault.

Answer 1

Have a read through this Ubuntu Community document on VPNClient. It's clear that the PPTP Client that joe suggested is what NetworkManager is using to manage your VPN connection to the PPTP server.

The document tantalizingly points out that you can configure part of your traffic to go through VPN and the other part to bypass it, but omits to say how:

More advanced routing is possible, with some traffic going over the tunnel, and some going out as usual, but this is not covered here.

A google search reveals that people have done similar stuff by configuring the routing tables or port forwarding. That stuff is beyond me. If you're interested, here's the HOWTO.

If you don't get an answer that solves your problem, and would like to try this, I'd suggest you ask this question over at ServerFault. Sysadmins are more likely to know how to configure VPNs and do VPN tunnelling.
