The Asus RT-AC56S router uses a firewall to help protect your local home network from unwanted Internet access. Your firewall does this by blocking any unauthorized connections. For example when you play an online game or use a program online and it doesn't preform as it should it may be that some of the connections to play that game or application are blocked. To fix this you need to create a port forward on your Asus RT-AC56S router.

In this guide we will show you exactly how to port forward on the Asus RT-AC56S. These steps include:

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

Now that you have setup a static IP address on the device you plan on forwarding these ports to, you need to login to the Asus RT-AC56S router in order to create the port forward.

Your device uses a web interface to make setting changes to the router. This means in order to access the router setup pages you need to open a web browser. It does not matter what browser you decide to open. I recommend picking your favorite. Some common options for web browsers are Internet Explorer, Google Chrome, Microsoft Edge, and Mozilla Firefox.

After you have chosen the web browser and opened it up, look for the address bar. This is normally at the top of the page 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-AC56S IP Address is:

Once you have clicked the Enter key on your keyboard, you will be given a login page like this:

Asus RT-AC56S Login
Asus RT-AC56S Login.

This is the router login page. Go ahead and type the router username and password in the spaces and press the blue Sign in button to access your router management pages.


The router username and password are not the same as the WiFi username and password.

Having Trouble?

If you are having trouble logging into the router setup pages here are a few options you can try:

  • First, if your router has a slightly different firmware version you may have a different username and password as well. We recommend trying other Asus usernames and passwords. Here is our list of the Default Asus Router Passwords.
  • If you are still unable to login to the Asus RT-AC56S router it is because you have changed the username and password in the past and don't remember. Why not try to guess what you changed it to? Need help? Use our Find Password App. It is quite handy in these situations. It does the guessing for you. Learn all about it on this Router Password Cracker page.
  • Still stuck? It may be time to consider a factory reset. This type of reset should not be done unless you have exhausted all other troubleshooting options. Everything is erased that you have changed in the past. This includes username and password, WiFi settings, DSL logins, port forwards, etc... Learn more about a reset on this How to Reset a Router page.

Step 3

By now you are logged into the Asus RT-AC56S router management pages. It is time to find the port forwarding section of the router. To help you do this we start on the Network Map 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 ports to forward into the Port Range box.

The ports can be entered as a list 23,24,25, a range 500-600, or a combination of both 23,45,500-600.

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.

When you are finished, click the + button.

When you are finished adding entries, make sure to click the Apply button.

That's it, congratulations on creating a port forward.

Open Port Check

After you have finished forwarding the ports for your Asus RT-AC56S router you should check them to see if they forwarded correctly. We recommend using our FREE Open Port Checker. You can find it as part of our trail version of the Network Utilities. Our port checker uses a local application to see if the server is listening. This positively guarantees whether or not your ports are open or not.
