piss easy, if you have public ip and basic computer knowledge. open port 9600 and 8081 on your pc and router, configure assetto corsa server (it has GUI configurator, can't get any easier), press start.

For extra easiness points, and some extra features like easily configurable day/night cycle, you can use Content Manager server GUI, but you have to pay a dollar or two to coolest ruski around to get full version of CM.
