Hi. You should download openvpn from
http://openvpn.se/ for example, to see the GUI.
Or, if you're in ubuntu linux just type "sudo apt-get install openvpn" and see what happens.
Then you should read the doumentation.
http://openvpn.net/index.php/open-source/documentation/howto.html#quick is a good start.
Then you should report back to this board if your internet connection becomes absolutely free. I would like to buy an account on your provider if that becomes the case. But I doubt it very much that it will happen. You will most likely have to keep paying for your internet.
