Configure your Computer to Have a Static IP Address

Port forwarding the Asus RT-N66U to your computer can be more reliable if you first configure a static IP address on your computer. We have instructions to setup a static IP address for Windows 7, Windows 8, and a variety of other devices on our Static IP Address Settings page.

Please note that while setting up a static IP address on your computer is optional, it is still a very good idea to go ahead and do it. In the long run it will make your port forward much more reliable.

To get started forwarding a port you need to login to your Asus RT-N66U router. If you are already logged in you can skip this step.

Next to this is the Port Range enter the port number in this box, if you are forwarding multiple ports then enter them in a list form such as 22,23,24, a range such as 22-25, or a combination of both 22,23, 25-27.

To the right of this is the Local IP enter the IP Address you are forwarding these ports to in this box. If you are forwarding a port to run a program on your computer, then you should use that computer's IP Address here.
