In-Home Streaming (help)

Hi, i've been looking around to find out if theres a way to stream our steam games over the internet, instead of just lan.

So what i've came across was OpenVPN bridge, the problem is, i never used a VPN before, even less configure it as a server...

The idea is to be able to go into a coffeshop or hotspot or w/e and be able to stream my games to my craptop, it works pretty well over lan, but cant figure out how to do it over ip.

If anyone have setup a bridge conection before can shed some light into the process? im using windows for both machines...

 

Also if the topic isnt in the right place, sorry.. please move it.
