I'm developing a multiplayer game based on the "Multiplayer_bomber" model.
I wanted to test on two machines connected by internet. I entered for the server the IP 127.0.0.1 and for the client the public IP of the server. Both machines are connected to the internet via boxes configured as routers. The client sends a "connection_failed" signal with the firewalls disabled.
The same application running twice on the same machine (with IP 184.108.40.206 on client and server) works perfectly.
I don't understand why. Can you help me?
