Sounds like your Firewall is blocking your Server partially. Make sure you have opened both ports in your firewall: The Port on which AssaultCube is listening plus that one higher. So if your server is using the standard port 28763 you have to open ports 28763 and 28764.
If that does not help: Is there any output in the servers console?
