Open Ports on the Linksys XAC1200 Router

This Linksys XAC1200 router has a firewall that helps keep your home network safe from any unwanted Internet access. The router firewall does this by blocking incoming and outgoing connections that have not been authorized. All the connections needed to surf the web and check your email are authorized, however some connections that allow for better online gaming or other online programs are not automatically opened. You need to open them by creating a port forward.

On this page I will show you exactly how to port forward on the Linksys XAC1200 router. I will walk you through each of the following steps:

  • How to setup a static IP address on the device you plan on forwarding the ports to.
  • How to login to the Linksys XAC1200 router interface.
  • How to find the port forwarding section of the device.
  • What information to enter for the port forward entry.

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.

TIP: You need this static IP address a little later in this process, write it down.

Step 2

In order to login to the Linksys XAC1200 router interface you need to open a web browser. It typically doesn't matter what browser you decide to use, I recommend picking the one you are most comfortable with such as Chrome, Internet Explorer or Firefox.

Once you have opened the web browser, find the address bar. If you don't know what this is, it is located at the top of the page like this:

I went ahead and circled the address bar for you in the image above. All you have to do is erase what is currently in that bar and type in the router's IP address. Don't know what this is? The router's IP address is also called the computer's default gateway or the router's GUI address.

By default the Linksys XAC1200 router has an IP address of:

After you enter the Linksys XAC1200 router's IP address, click the Enter key. This should give you a login page similar this:

Linksys XAC1200 Login

If a login screen did not appear after you entered the router's IP address in the address bar, you need to find out what the router's IP address has been changed to. I recommend following the directions on the How To Find Your Router's IP Address page.

Go ahead and enter the router's login password.

  • The Default Linksys XAC1200 Router Username is: admin
  • The Default Linksys XAC1200 Router Password is: password

Click the blue Sign In button to access the router's web interface.

Having Trouble?

This is a pretty common place to get stuck. If you find yourself here, don't panic, there are a few things you can try:

  • First, check all the different Linksys default passwords. Here is our list of all known Default Linksys Router Passwords.
  • Second, try and guess what the password was changed to. Use our Find Password App to make this step easier.
  • Finally, if you still are stuck after trying both of the above options, it may be time to consider a factory reset. Learn more about this option on the How to Reset a Router page.

Step 3

It is now time to find the port forwarding section of the router. To help you with this step, we begin on the Home page.

Linksys XAC1200 Home

From the Home page, click the option of Security in the left sidebar.

Linksys XAC1200 DDNS

Now select the option of Apps and Gaming at the top of the page. Then under that select either Single Port Forwarding or Port Range Forwarding below that.

Linksys XAC1200 Single Port Forwarding

The image you see above is the Single Port Forwarding page.

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:

Forwarding a Port Range

You need to name this entry in the Application Name box. The name does not make any difference in the forward; it's just there so that you can remember later why you setup this forward.

If you are only forwarding a single port number then enter that number into both the Start Port and the End Port boxes. If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Start Port box and the highest number of that range into the End Port box.

In the Protocol box select the protocol that you want to forward these ports over.

You need to enter the IP address that you are forwarding ports to in the Device IP# box. It's possible for this to be either the IP address of your computer or any other IP address on your network that you want ports forwarded to.

In the Enabled checkbox put a checkmark.

When you are finished, click the Save button.

Forwarding a Single Port

You need to name this entry in the Application Name box. The name does not make any difference in the forward; it's just there so that you can remember later why you setup this forward.

Enter the same port number to be forwarded into both the External Port and the Internal Port boxes.

Select the protocol type of the ports you are forwarding from the Protocol box.

Enter the IP address to forward these ports to into the Device IP# box. If you are forwarding ports so you can run a program on a device other than your computer then you can enter your device's IP address into that box.

Put a checkmark in the Enabled checkbox.

When you are all done click the Save button.

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

Test Your Ports

Are your the ports you just forwarded really open? An easy way to find out is use our free Open Port Checker. It uses a local application to see if the ports are open or not. This guarantees our port checkers accuracy.
