Multiplayer Guide?
 

Is there a guide somewhere for how to get the multiplayer to work? A lot of the information seems kind of old and outdated, and my friends and I are trying to get it to work. I've put in his IP Address and nothing comes up, and the game wont let me host either. Any advice or a a comprehensive guide anywhere on what to do?

If You haven't external IP You can't host DW.
Another way for connection is for ex. Tunngle.
