How to Port Forward a Linksys WRT120N Router

Linksys WRT120N routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.

The basic process to open a port is:

  1. Setup a static IP address on either your computer or device that you want to forward a port to.
  2. Login to your Linksys WRT120N router.
  3. Navigate to the port forwarding section.
    • Click the Applications & Gaming link.
    • Click on Single Port Forwarding or Port Range Forwarding.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Linksys WRT120N 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 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

Now we are going to login to your Linksys WRT120N router. Your router has a web interface, so you will login to it using your web browser. This can be either Chrome, Firefox, Internet Explorer, or Edge. It usually does not matter which browser you choose to use.

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


192.168.1.1

In the picture above the address bar has 192.168.1.1 in it. Just replace all of that with the IP address of your Linksys WRT120N router. Your router's IP address can also be refered to as your computer's default gateway.

By default the IP address is set to: 192.168.1.1

After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:

Linksys WRT120N

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

  • The Default Linksys WRT120N Router Username is: admin
  • The Default Linksys WRT120N Router Password is: admin

Enter your username and password, and then click the Login button to log in to your Linksys WRT120N router.

Linksys Usernames and Passwords

If your username and password do not work then please visit our Default Linksys Router Passwords page.

If you still can't login to your router because you forgot your Linksys WRT120N router username and password, use our How to Reset a Router Password guide to set your Linksys WRT120N router back to its factory settings.

Step 3

Now we need to find the port forwarding section in your router. Here's how you do it. Starting from the first page in your router:

Linksys WRT120N

Click the Applications & Gaming link near the top of the page.

You should now see a new menu. In this new menu, click Single Port Forwarding or Port Range 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:

Forwarding a Port Range

You need to name this entry in the Application 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 just forwarding a single port number then you can simply enter that same number into both the Port Range Start and the Port Range End boxes. If you are forwarding a range of ports, usually separated by a hyphen, then you need to enter the lowest number of that range into the Port Range Start box and then enter highest number into the Port Range End box.

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

Enter the IP address that you want to forward these ports to into the IP Address box. Note that 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 instead.

In the Enabled checkbox put a checkmark.

Forwarding a Single Port

Enter the name of the program into the Application box. It doesn't really matter what you put into this box, but something that will remind you why these ports are being forwarded is be a good idea.

Enter the port to forward into 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 that you want to forward these ports to into the IP Address box. Note that 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 instead.

In the Enabled checkbox put a checkmark.

When you're finished, click Save Settings near the bottom of the screen to save your changes.

Test if Your Ports are Open

Now that you have forwarded ports on the Linksys WRT120N you should test to see if your ports are forwarded correctly.

To test if your port has been properly forwarded, you can use our Network Utilities tool, which includes a free Open Port Checker. Our Open Port Check tool is the only online port checking tool with Guaranteed Results.
