just installed the Unreal 3.2 server on windows 2003 server in the local network. i can connect locally with no problems. i cannot connect using port 6667 from a client in the local network. i did both try the server name and the ip.
i can connect using the port 80 in the local network from a client.
i did run a port scanner on the server and this tells me that the port 6667 is open and reachable.

the windows firewall does not run on the server!
what can be the reason for this issue? thanks in advance, roland.
