normaly I dont register on Forums as google pretty much knows most of the answers I need for my every day Problems with setting up certain Software. But oh boy... ArmA 2: OA Dedicated Server (For Windows) sure gives me a run for my money.
I think I read pretty much every thread in this (and other forums for that matter) regarding the topic and it seems that there is no solution whatsoever to that Problem.
Also one side is blaming Gamespy, the other BIS. Infinite Loop comes to mind... oh well, I am already this close doing some physical harm to my server that I had to post this to relieve some stress.
I try to provide as much Information on the matter as I can remember.
1.) The Game is bought via Steam.
2.) I downloaded it via Steam on my Windows Server 2008 RC 2 (incl. the dedicated Server)
3.) I set the Windows Server Firewall to accept every incoming AND outgoing TCP & UDP Port for ARMA2OASERVER.exe
4.) I configured my Router to forward Ports (UDP, UDP & TCP) 2302, 2303 and 2305 to my Server.
5.) I even tried opening the Ports needed for the Gamespy Servers. Also both TCP & UDP.
6.) The Dedicated Server is configured with TA2DST (Port 2302). No Mods are installed. Vanilla installation.
7.) The Clients are Vanilla aswell.
8.) Connecting via LAN works like a charm
9.) Internet Searching in the Gamespy Server list, works. BUT The Ping is either "?" or 2500
10.) Connecting results in "Connection Failed" and the RPD (I think it was called) says
NAT Negotiation failed - unable to communicate with the server
NAT Negotiation failed (NNThink - result 2)
11.) Doesnt matter if I try to connect or my friends. We all get the same error.
I hope that is something to work with.
Some of the solutions I have found contain thinks like "Open UPNP Ports" or "Enable UPNP"
Well... not an option realy. Also, my Router has no ICMPv4 nor ICMPv6 settings.
Oh yeah, it's a Alice Modem WLAN 1421.
Like I said before, I am this close to loosing it so this is pretty much my last shot at getting it somehow fixed.
Suggestions are highly appreciated!
