Serving a VPN connection through a Linux PC

ledimies

Hi,

I have a Linux PC with two ethernet ports, eth0 and eth1. Eth0 is connected to a router that acts as internet access point. I also have access to VPN server(s). I want to achieve the following:
- PC is connected to the internet via eth0.
- VPN connection is up and running.
- Any internet traffic generated directly from PC (web browsing, etc...) does not use VPN tunnel.
- Any device connected to eth1 does use VPN tunnel.

So what I'm trying to do here is to set up a server (not a OpenVPN server, but server non the less) that provides an internet connection that uses VPN connection to devices that are connected to eth1. The server itself does not route it's traffic through the VPN tunnel. Only the devices connected to the server use the VPN tunnel.

Is this possible? I've tried to find tutorials and examples of this kind of setup, but I haven't found one. Can someone here point me to the right direction?

Thank you.

Yes, I am using PC with a recent Ubuntu distribution and I have OpenVPN installed. I am able to create a OpenVPN tunnel using a third party VPN service. I have no control over the server settings.

One of the many commercial VPN providers like privateinternetaccess, astrill, strongvpm, hidemyass, ivpn, purevpn, expressvpn, etc.

I found out that there is another way of acheiving what I really want. I can connect to the OpenVPN server of my choosing and with some iptables rules (that I found here) I can use the linux pc as a gateway to a router that is connected to the same subnet as the pc. So all of the router's traffic goes through the OpenVPN tunnel, which is what I want. This way I don't even need two network interfaces in my linux pc.

I still need to figure out how to set-up the iptables rules so that I can use the linux pc as a gateway to the OpenVPN tunnel but still the linux pc itself doesn't use the OpenVPN tunnel.
