Today I will show you how to portforward on your AT&T U-Verse Internet Router.
You'll need a couple things:
(1) An Internet Browser
(2) Password to your router (not to connect to the Internet, the one that's on the router itself)
(3) A Minecraft Server to portforward to.
This technique works for a lot of servers, such as FTP, SFTP, HTTP, DCHP, IMAMP, SSL, and more!

Can't find your router administrative password?

Where I blocked out in green should be the numeric password that I used to use the advanced configuration (portforwarding).
In other words, the password that I typed at 3:06
