I have tried many multiplayer sources. pun2free,... until now, netcode for gameobjects. the official unity multiplayer thing I think. So the problem.. it works perfectly fine in my own internet, at the same pc, if I open the game twice, one host and one client. but.... here's the catch: if i open my game with host on my pc, and a other guy, which is in a different internet and pc, I dont show up. like nobody would play. do I have to set th up? did I miss sth? please help! 2 games in my pc working without any issues when I want to play with some friend not in my internet: he just doesnt show up.
