It is easier if your Router supports VPN termination after you basically
1. Set up Dynamic DNS this is free no-ip.com have free ones
2. Configure a VPN Server on the Router
3. Set up the Client your friends tool
4. Connect
The benefit of this is that you can in a minute connect to these files from virtually anywhere on the internet. Cafes, work (if they allow VPN traffic out)
I do this in a minute but use a slightly more expensive Cisco Router as my VPN server.

You can use free VPN software to do it and you can use free DNS servers as all right, to point to your router. The end item you will hold to do is setup your router for port forwarding. If you enjoy a firewall on your computer and one surrounded by your router and you dont own them setup to permit a abiding port through, they will block the traffic, any lacking letting you know at adjectives or beside a popup, maxim that you are anyone attacked. So pickup some free VPN software, setup port forwarding on your router, setup your firewall to consent to the software program transport and recieve traffic, and you should be devout to progress.
