I can't join games and it shows me this problem: Failed to establish a direct connection with icarocard. Traffic to this user will go through the fast proxy server. If you have trouble connecting with many different users you have a problem! To resolve this, it is recommended that you forward a port in your router for UDP port 16000. You are also advised to run the Network Diagnostic Tool>. Does someone had similar problem please tell me what to do. I have port set to 16000 but it can't be this problem because I'm not using Wi-Fi. Administration also didn't help me.

Please paste us the results of the network diagnostics. Thanks.
