I thought about it again and I noticed something I also did before everything started working fine. I just installed gamespy.. Perhaps the standalone version of gamespy is important for online playing? Would be interesting to know, whether all players, who don't have gamespy installed, are experiencing problems... I mean that would be less weird than my last solution, maybe ArmA uses some external gamespy stuff, although it shouldn't...

I fixed the problem.. but the solution is such unbelievable.. I really don't know if really that was the fix.. I closed all the ports but 2302 and now I can join every game

Yes, that's the funny thing. Yesterday I had the same problem, I couldn't connect to servers. Then I patched the game, tried to connect and evrything went fine. As I left the server there was the same problem as before...

Hi! Everytime when Arma tries to establish a connection it fails and I'm thrown back to the server list. That problem seems to me quite strange, since I yesterday could play online (but also on only one server, maybe I was lucky). So my question is now what am I doing wrong? Thre is no firewall running or something like that. On the router I opened the ports 27900 - 29901 13139 6515 6500 3783 6667 2000-3000 6073 I found them in some forums, but they didn't help. I'm alreay trying to play online for 6 hours and now I have no more ideas what to do... So who can help?
