I got it working using a vpn game program called Evolve. It's like hamachi but thi actually worked. https://www.evolvehq.com/ Go there, get the client and register. The run the program make a party room and invite your friends to it. Once all are in the party room all can launch the game. You shoud see a 10. IP in multiplayer screen meaning its working. Host can setup a game and all ahould be able to see the game in the list without putting in the ip just refresh until it shows up. Already tested on a couple of 5-6hr long games and no problems at all.
