As I needed to have my home HVAC server always reachable and keeping in mind that it’s on a dial-up connection (dynamic IP) I decided to build virtual private network. The main goal is to get the home computer visible from the server as it was in local network. Don’t worry, it’s much easier than it seems. Thanks to detailed HOWTO it took me less than 1h to build working connection.

As it’s to easy to do and to long to describe I won’t post detailed description. Just go to the howto and follow the instructons step by step.
