I use PIA and I have found this link while searching though about setting up Ubuntu Linx and it is a shame that the vpn set-up on my M10 is not as easy as this, https://www.privateinternetaccess.com/pages/client-support/ubuntu10.10-pptp
However, in the Advanced Open VPN section i have Ino idea which file to downloead and use. I would assume that i need the tcp/strong file but with vpns i do not want to get it wrong.
