I've been testing and emailing the devs regularly. I got the router to work without the evolve program and tested with two guys.
I do not recommend this method to anyone who is not comfortable with the risk.
I made several changes to my router.
1. I port forwarded 7777, but when starting the game, we randomly picked port 1234, so all players entered 1234 instead of 7777 and it worked if I was the host, but not if the other guys hosted. Probably because of step #2
2. I set my router to DMZ.
3. All three of us tried to run the game in administrator mode, by right clicking the .exe and choosing run as admin.

My belief is that because I also opened my router to DMZ- demilitarized zone which is dangerous as far as being attacked by viruses, or pirates, that I had more success.
Some of these changes introduced variables that I have not weeded out completely.. still testing variations.
Not all routers have the same success, some are poorly designed, work unreliably, or have less software switches inside for choices..
