Simple Asus RT-AC1200 Router Port Forwarding Instructions

This Asus RT-AC1200 router uses a firewall to help protect your home network from unwanted Internet access. This firewall does a good job of keeping unauthorized connections blocked. If you notice that while using an online program or playing an online game it lags or completely kicks you out, it is because you need to open some of the blocked connections. This process of unblocking a connection or opening a port is called a port forward.

In this guide we will show you exactly how to setup a port forward on your Asus RT-AC1200 router. We will walk you through the following steps:

  • How to setup a static IP address on the device you are forwarding these ports to.
  • How to login to the Asus RT-AC1200 router.
  • How to find the port forwarding section of this particular router.
  • How to configure the router to forward the ports you want unblocked.


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 guides to setup a static IP address.

After setting up a static ip address on your devices you need to login to your router.

Step 2

After you have setup that static IP address, it is time to login to the Asus RT-AC1200 router. Your router uses a web interface to manage the settings, which means you need to login using a web browser. It doesn't matter which browser you decide to use, simply pick your favorite. Some of the more common options are Chrome, Internet Explorer, and Firefox.

Once you have decided what browser to use, open it up and find the address bar. This is normally found at the top of the page:


192.168.1.1

In the above image, the address bar has been circled for you. Once you find it on your web browser page, replace what is in there with the router's IP address. Don't forget the router's IP address can also be called the default gateway or the router GUI address.

The default IP address for the Asus RT-AC1200 router is: 192.168.1.1

If the default IP address for the Asus RT-AC1200 did not work or you know you changed it in the past but don't remember what you changed it to, you need to find out what it is. This How To Find Your Router's IP Address guide does just that.

Once you have entered the router's IP address into the address bar, simply click the Enter key on your key board. At this point you should be taken to a login screen like this:

Asus RT-AC1200 Login

Enter the router's username and password into the spaces available and press the blue Sign in button to access the router's user interface.

  • The Default Asus RT-AC1200 Router Username is: admin
  • The Default Asus RT-AC1200 Router Password is: password

Having Trouble?

Don't worry this is a very common place to get stuck when trying to login to the router. Here are a few things you can try:

  • As a first step, we recommend trying other Asus default username/passwords. If you have a different firmware version you could have a different username or password as well. Here is our list of all the Default Asus Router Passwords.
  • If that did not work, it is because you changed it in the past and don't remember what you changed it to. Try guessing what you would of changed it to. Need help? Use our Find Password App. It automates the long process of guessing thousands of different combinations for you. Learn all about it on our Router Password Cracker page.
  • Finally if nothing else is working to get you logged in, it may be time to consider a factory reset. A reset like this is going to erase every single setting you have ever changed in the history of this router. To learn how to reset this router, read this How to Reset a Router guide.

Step 3

Now that you are logged into the Asus RT-AC1200 router you need to navigate to the port forwarding section of the router. To help you we begin on the Network Map page:

Asus RT-AC1200 Network Map

On this first page, look in the left sidebar. Over half way down the screen pick the option of WAN.

Then click the tab at the top of the page labeled Virtual Server/Port Forwarding.

On this page, pick the Yes option next to Enable Port Forwarding.

Step 4

Here are the ports to forward for Xbox Live:

TCP Ports:3074
UDP Ports:3074

If you are looking for the ports for a different application you can find it by either:

Make up a name to put in the Service Name box. The name does not have any effect on the functionality of the forward, it's simply there so you can know why it was created.

Put the ports to forward into the Port Range box.

You can enter the ports as a list 23,24,25, a range 500-600, or a combination of both 23,45,500-600.

Enter the IP address that you are forwarding ports to in the Local IP box. This is either the IP address of a computer or the IP address of another device on your network.

From the Protocol box select the protocol for the ports that you want to forward.

When you are finished, click the + button.

Finally, don't forget to click the Apply button to save your changes.

Test Your Ports

It is now an excellent idea to test those ports to see if they forwarded correctly. We recommend using our Open Port Checker. It's FREE and part of our trial version of the Network Utilities Bundle. Our port checker is better than the others you find online because we use a local application to see if the ports are open or not. This GUARANTEES a open port verification.
