My friend told me, that without public IP of the workstations, I can access machines remotely. But I'm a rather confused in using VPN, I don't understand how can it manage to connect. I saw this video about VPN's mechanism, but he didn't mentioned building them.

The situation is:

• I have an office, with its workstations. Sure, the computers are connected to the Internet.


• I have computers at home, and my other working places with Internet access.

How can I access the office machines with VPN without server with public IP from everywhere? Can you show me a complete tutorial?

(I saw TeamViewer, Hamachi, but if it possible, I want to use a private VPN.)

Thank you very much!
