Spring RTS Engine

the IP the server is detecting you with might be different. Try inputting it manually to the Configuration dialog. Also, double check the port forwarding and the firewall settings. checked and double checked. Inputting into the configuration dialog didn't help. All the ports in the "ports"...

I click host, type in game name and such, click test, and it says:
Failed. You probably won't be able to host with these settings
I have the correct port forwarded on TCP and UDP. What else could be the problem?
