The Asus RT-AC56U router has a firewall that helps to protect your home network from unwanted Internet access. Firewalls block incoming connections that you may want unblocked. This process of opening a port is frequently called a port forward. You can learn more about this topic on this page. Very basically, a port forward forwards your port from the Internet to a device on your network.

Here on this page we will be walking you through each of the steps involved in getting your ports forwarded.

We will show you how to:

  1. Setup a static IP address on the device or computer you want ports forwarded to.
  2. Login to your Asus RT-AC56U router.
  3. Navigate to the port forwarding section.
    • Click WAN
    • Click Virtual Server / Port Forwarding
  4. Enter the data to create a Port Forward

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.

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 faster than ever 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

Login to the Asus RT-AC56U router.

In order to login to this Asus RT-AC56U router you need to first open up a web browser because this router uses a web interface.

It does not matter what web browser you decide to use, there are a lot of different choices. Some common options are:

Open up your web browser and find the address bar. It should look something like this:

Above is an example of what a web browser address bar looks like. Find the address bar in your router and type in your router's IP address.

The default Asus RT-AC56U IP address is set to:

After entering the IP address of your router you can simply press the Enter key. If all goes well you should see the following screen asking for a username and password:

Unless you have changed these values go ahead and enter the default username and password for the Asus RT-AC56U router.

Once you have finished entering the username and password go ahead and click the OK button to login to the router web interface.

Having Trouble?

This is a common place to get stuck so we've added a few troubleshooting options you can try:

  • If you were unable to login to the Asus RT-AC56U router we recommend trying other Default Asus Router Passwords. It is possible different firmware versions have a different username and/or password.
  • If you are still locked out of your router it is possible you changed the username and password in the past and have forgotten. We recommend trying to guess your password. To help with this process we have a Find Password App that automates the long process for you. In order to prevent illegal activity The Find Password App is limited to only working on devices on your local area network. It will not work over the internet. Learn more on this Router Password Cracker page.
  • Finally, if nothing else works, you may need to consider a reset. This should only be used as a last desperate attempt to access your router. A reset erases everything you have ever changed on the device, possibly even ISP data you may be unaware of. If this is where you are at, then learn how on this page.

Step 3

Navigate to the port forwarding section

It is time to find the port forwarding section of the router. To do that let's start on the following page:

Create a name for this forward and put it in the Service Name box. The name is only used as a reminder and has no effect on the port forward.

Enter the port to forward into the Port Range and the Local Port boxes.

Enter the IP address of the device that you want to forward ports to into the Local IP box. This can be either the IP address of your computer or the IP address of another device on your network.

Select the required protocol for these ports from the Protocol dropdown box.

Click the Add button when you are finished.

When you are finished, click the Apply button to save your changes.
