In this guide we show you how to properly open a port for the Asus RT-N66U router.

Your Asus RT-N66U router has a basic Firewall. This firewall blocks unwanted access from the Internet. To unblock a connection that is normally blocked, you need to tell the firewall to keep that port open. This process of opening a port is frequently called a port forward. When you port forward you are telling the firewall to let that connection go directly through the firewall to a device on your network.

To open a port for the Asus RT-N66U router you need to:

  1. Setup a static IP address on the computer or game console you want these ports forwarded to.
  2. Login to your Asus RT-N66U router.
  3. Find your way to the port forwarding section.
    • Click the WAN button.
    • Click on Virtual Server / Port Forwarding.
  4. Make a port forward

Don't worry, we will be walking you through each and every step in the process to get your ports open on the Asus RT-N66U router.

We think that forwarding a port should be easy. That's why we created Network Utilities. Our software does everything that you need to forward a port.

Step 1

It is important to setup a static ip address in the device that you are forwarding a port to. This ensures that your ports will remain open even after your device reboots.

This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

NordVPN birthday deal!

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

Step 2


In order to login to the Asus RT-N66U router you need to use a web browser because this router utilizes a web interface.

Go ahead and open up your favorite web browser. This could be Chrome, Edge, Firefox, or Internet Explorer. It really doesn't matter what browser you decide to use.

After opening your browser you have to find the address bar. This is normally located along the top of the page, like this:

After putting the IP Address of the Asus RT-N66U in the address bar, click the Enter button on your keyboard. You should then see the following screen:

You are on the right track if you see a box asking for a username and password.

Enter the username and password and click the OK or Login button to access the web user interface of the Asus RT-N66U router.

The Asus Username and Password Do Not Work

If the username and password did not work, we recommend trying other common Default Asus Router Passwords.

If you still are having trouble accessing the web user interface it may be that you have changed the username and password in the past and have forgotten. It might be time to consider a reset. To learn more about this and how it affects your router, check out this How to Reset a Router guide.
