So I've been having this issue for a while and the internet has been mixed for a response. Sadly most configurations for setting up a VPN seem to assume you are running both a vpn client and server and have access to both. I have a provider that I have signed up for.

I know the configuration of the open vpn file is accurate and the authentication since it works on several android devices. I can get this working on linux as it authenticates and creates a tun0 interface but I can't do anything with it.

I have tried various redirect attempts from examples on the internet but sadly they seem not to work, route, resolve DNS addresses, etc. Basically the connection dies when it's active and comes back when it's gone.

This is being done in a VirtualBox instance as a guest interface and a host interface of Windows 7.

No problems with the routes on either one and no issues with unbuffered internet access on both without the VPN.

See this list of possible interfaces:

~$ sudo ifconfig -a

How shall I basically setup a bidirectional connection betwen the tun0 and eth0 that will not fail terribly?
