Configure your Computer to Have a Static IP Address

Port forwarding the Asus RT-AC66U 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-AC66U router. If you are already logged in you can skip this step.

The next box is called Port Range. Enter the port range that you are forwarding here. If it is more than one port then enter it with the lowest number to the left with a dash then the highest number, such as 22-25.

Next is the Local IP. Enter the IP Address that you are forwarding these ports to. For example if you are using these ports to run a program on your computer, then use that computer's IP Address.

In the Local Port box do the same thing you did with Port Range. Enter the range of ports you are forwarding here separated by a dash. Lowest number, dash, highest number.

Protocol is next, use this drop down menu to choose the type of protocol you want to use.
