Please go to the computer your server is on.
If windows: go to start, command prompt, and type "ipconfig"
Get the IP address and write it down.
Go to your computer and type in tremulous console "/connect ipaddress" <-- Not IPaddress the address from ipconfig.
If that fails try to connect with your public IP.
Make sure that everything is right now!
And also can I have the IP of this server, I want to see if I can view server.
