Server Connection failed problem.

[pepperana 0]

Hi ArmA 2 players.We need your help.

Our Dutch tactical gaming community has a problem with our server.

Our server has a very strange problem.

When players want to join the server, some are connection without any problems. But at least the half are getting the 'Connection failed' error.

We started the server about 2 months ago and nothing was wrong.

About a month ago the connection failed problem start kicking in.

I had the problem to. But the strange thing is that the problem is only on our server.

There is no other server in the list that I can't connect. And that also counts for the rest of the p members that have the problem.

I tested the server with different kind of profiles etc no result.

The only thing that solved the problem was that I opened my client ports:

That did the trick for me. But why do I have to do that for our server only?

On all the other servers I don't have to open the ports.

On our server the following ports are forwarded:

2302-2303-2304-2304

This is our server:

Can someone point me in the right direction?

I see the same problem alot on our dutch I3D server aswell. Usualy the first time a user connects they get this message but the second try is always a sucsess. This might be the answer already tough! Normaly you would expect your router to auto port forward any incomming or outgoing transmission if you have exepted the Windows firewall permission it promts you with the first start to play Arma2 online. Does your router support uPnP ? I think this function enables the system to route true the switches firewall without the need of port forwarding.

You could check:

-In windows firewall if Arma2 has been exepted proparly

-If your using XP if uPnP is installed: http://support.microsoft.com/kb/941206

-A Firmware update for your router / modem (always ask the owner of the device for permission)
