Get Open NAT on AT&T U-verse

Open NAT AT&T U-verse

Every computer including your computer has private IP address which is basically used to uniquely identify your computer on the Internet. AT&T U-verse router on the other hand also has a shared public IP address.

Your private address is replaced with the public address by the router when you send any information or data to the Internet. But when the information is received the router puts the private address back and routes the data. If the router didn’t assign the port number, it drops the data. This is the process which is known as Network Address Translation and it creates a natural firewall. If the game, you are playing, communicates over a specific port, you must open the port that tells the router not to perform NAT and to send the traffic on the port directly.
