How to Port Forward on the Asus RT-N56U

Your Asus RT-N56U router includes a firewall that helps to protect your home network. A firewall's job is to block potentially dangerous connections to and from the Internet. By default some of the safer connections have been opened so you can use the Internet. However there are times you want some of the blocked connections opened. This process of opening a port or connection is called a port forward because you are forwarding a port through the firewall and sending it straight to a device on the network.

We will go over how to:

  1. Setup a static IP Address on the device or game console you want to have these ports forwarded to.
  2. Login to your Asus RT-N56U router.
  3. Navigate to the port forwarding section.
    • Click the Advanced Setting button.
    • Click on WAN.
    • Click the Virtual Server button.
  4. Finally, what data to enter to get your ports forwarded.

We will be walking you through each and every step in the process to getting your ports forwarded for the Asus RT-N56U 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.

When you use Network Utilities you get your port forwarded right now!

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.

  • Recommended - Our free program will setup a static IP address for you.

  • Or follow our Static IP Address guide to setup a static IP address.

Step 2

It is now time to login to the Asus RT-N56U router. Your router uses what is called a web user interface. What this means is you need to use a web browser to access the router interface.

Go ahead and choose your normal browser and open it up. Common web browser choices are: Chrome, Edge, Internet Explorer and Firefox. It shouldn't matter what browser you want to use, just pick your favorite.

Once you have opened the browser of your choice, find the address bar at the top of the page. It should look like this:

192.168.1.1

In the image above, we have circled the address bar for you and it has 192.168.1.1 in it. Simply replace all of that with your router's IP Address or router's gateway.

If you have changed the router's IP Address in the past and don't remember what you changed it to, find out how to retrieve it in our How To Find Your Router's IP Address guide.



If you have never changed the router's IP Address...

The default Asus RT-N56U router IP Address is: 192.168.1.1



After entering the IP Address in the address bar, click the Enter key on your keyboard. The following box appears:

You should see a box prompting you for a username and password.



  • The Default Asus RT-N56U Router Username is: admin
  • The Default Asus RT-N56U Router Password is: admin


Enter your username and password, and then click the OK button to access your Asus RT-N56U router.

Trouble Logging In?

This is a common place to get stuck. Here are a few things you can try:

  • Try other common Asus username/password combos. Router firmware updates sometimes change the username and password. Here is our list of Default Asus Router Passwords.
  • If other Asus passwords did not help you log in, it could be that you changed the username and password in the past and have forgotten. If this is the case, why not use our Find Password App. It automates the process of guessing different combos for you. Learn more about this on this page.
  • Finally, if nothing else worked, you may need to consider a reset. A factory reset like this one erases all personal data and maybe even ISP data you are unaware of. We strongly suggest trying other options before resorting to a reset. Learn the basics of resetting a router in our How to Reset a Router guide.
Step 3

It is now time to find the port forwarding section of the router. To do that, let us start on the first page:

First, click the Advanced Setting button in the left sidebar menu.

Then, under that click the WAN option.

Finally, click the Virtual Server tab at the top of the page. This should take you to a page like this:

Step 4

After successfully navigating to the port forwarding section of your router you need to start entering the appropriate data into your router. In order for us to show you exactly how to configure the router you need to answer a couple questions:

Application :
IP Address :

(The IP Address above is the Static IP Address you setup in Step 1)

Below is our router simulator. Based on how you answered the above questions the router simulator will show you exactly what to enter to get your ports forwarded. Right now we are showing the ports for XBox Live. All you need to do is fill out the boxes in your router exactly as you see them here.

Once you have finished, click the Apply button to save your changes.


Test if Your Ports are Open

It is always a good idea to check your work. Did those ports forward correctly?

To test the ports to see if they forwarded correctly, we recommend using our free Open Port Checker. This can be found in our free trial version of the Network Utilities. Not only is this Open Port Checker free but it is Guaranteed to work.
