I want to set up an FTP Client Server that can be accessed via a VPN. My intent is to send data back from foreign countries tied back to a server that we control. I want to avoid using Emails because you really never know who has access to your info....especially in foreign countries who have no constraints on their privacy laws.

I've seen this VPN straight to a client server computer done before. ...just don't know the specifics for setting it up. Any advice?
