How do I port-forward on an at&t U-Verse router?

[chadmaverick]

After changing the router for faster internet connection, I could not host a server any more due to it. My friends say they have been stuck at "sending challenge request" and are unable to join. I was fine before but now I can't host. Please help?

this is a question for google not here
badspot already made a topic on why there is no reason for port forward topics
