OK, I did the port forwarding thing, and the server displays this:
Adding master server 72.165.61.153:27015
Adding master server 63.234.149.83:27011
Connection to Steam servers successful
VAC secure mode is activated.
However, when I put "steam://connect/72.165.61.153:27015" or "steam://connect/63.234.149.83:2711" it says that the server is not responding. Also, neither 72.165.61.153 nor 63.234.149.83 is my IP address...I tried that too.
