Ubuntu 14.04 - Looking for VPN for Virtual Private Server

Hey All,

Just signed up for a Ubuntu 14.04 VPS with a static public IP and I am looking for a way to setup a VPN I can connect into. Can anyone recommend a method in which I can setup a VPN To connect into? What would I need to do with the Public IP? Do I need to assign a second address of a private subnet and use that for the clients connecting? Anyone have any good guides on the matter?

Thanks
