Server no incoming connections

Hello, I need some help to figure out how to check if Xonotic accept or not the incomming connections, when I join a server it's okay all works fine.
I'm using Xonotic 0.5 on Windows 7 x64 at the moment.

And when I create a server it seems no one can access it. I've tried a long time ago with a friend but it works on half-time.

Thanks in advance

You should definitely use 0.6, 0.5 is fairly outdated!

I'm not sure in fact if I have already updated it or not, I download the 0.6 version, test it and keep you informed.

You need to open port 26000 UDP in your router. Also check your firewall software if you have any.

If your server is set to be public, you will know it's working when it shows in the server list here: http://dpmaster.deathmask.net/?game=xonotic

Can I ask you how you're launching your server? Have you read the documentation in the server directory?

The problem is still there, it seems nobody can join the server, I've checked the NAT rules and firewall to fit to Xonotic, I don't know where the problem comes from.

How are you launching the server? Have you read the documentation?
