I set up my dedicated server using this tutorial http://www.facepunch.com/showthread.php?p=10714706 I have successfully forwarded these ports: 1200, 27000-27015, 27020-27039 I have disabled all antivirus software as well as the Windows firewall. But my friend is still unable to join. He's tried connecting through friends, typing "connect xx.xxx.x.x" in console and he's tried looking in the server list but he couldn't find it. I have tried typing in "sv_lan 0, sv_region 0, heartbeat 1" In console but he still cannot join. The server ip is always this "192.168.0.3:27015" which my friend who owns a server says is normal. I tried giving him my IP address from www.whatismyip.com but he got the same error "failed to connect after 4 retries" or "not responding" Here's the port forwarding: I have no idea what it is, and neither does my friend who owns a server. I'm sure there are some people in this forum who own a server, can you please help me with this? I've posted this on at least 3 other forums but people rarely reply and they're suggesting stuff I've already tried. This forum is my last chance, please help.
