Fireball dont get me wrong I am trying to understand but I really dont get how they can not have aabsolute power about it. In none other steam games that I own have I experienced such a problem. Nor the develoopers have suggested me to use some other ways dont work at the end. can someone please enlighten me how I am able to play every toher game in my steam library but not Arma3 ?

First of all thanks devs for the hotfix. But unfortunately it still is not working for me. I cant see friends friends cant see me(listen server). Even through remote IP adress. I cant forward ports because my flatmate doesn't have the username and password for the router but my friends tried it and that also is still not working for us. Also when we play with the clan and search the (dedicated) server via filter it takes forever to find the server.

I have tried from in game IP search to Steam server search various things but neither my friends nor I can find the servers we open. the only thing that I haven't tried (and as it seems it works) is hamachi but I really dont want to install a third party program to make a program(which I bought) work!!
