Open Ports on the Linksys WRT54GS

Please select a firmware version:

The Linksys WRT54GS router has a firewall that protects your home network by blocking incoming and outgoing connections that are not authorized. Some online games or programs require additional connections to be opened so they can run smoothly. The process of opening additional ports is called a port forward.

In this guide I will be showing you how to port forward on the Linksys WRT54GS router. The steps I will walking you through are:

  • setup a static IP address on the device you plan on forwarding these ports to.
  • login to the Linksys WRT54GS router web interface.
  • find the port forwarding page in the router's web interface.
  • setup a port forward for the online game or program of your choice.

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.

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.

  • Or follow our Static IP Address guide to setup a static IP address.

TIP: Write this static address down. You need it later in this process.

Step 2

Now we are going to login to your Linksys WRT54GS router. To open the router interface you need to open a web browser. It normally doesn't matter which one, simply pick your favorite such as Internet Explorer, Chrome, or Firefox.

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

As you can see in the image above, the address bar has in it. All you need to do is replace what is in this bar with your router's IP address (also called the computer's default gateway).

By default the Linksys WRT54GS IP address is set to:

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

You should see a box prompting you for your username and password. If you do not see a login window similar to the one above, the wrong IP address was used. To find out what your router's current IP address is follow the directions on this How To Find Your Router's IP Address page.

  • The Default Linksys WRT54GS Router Username is: blank
  • The Default Linksys WRT54GS Router Password is: admin

Enter your username and password, and then click the Login button to log in to your Linksys WRT54GS router.

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 combinations. Here is our list of all known Default Linksys Router Passwords.

  • Second, try and guess what the password/username 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

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

A new menu appears. Click the option of Port Range Forward

You are now on the correct page to make a port forward entry.

Step 4

Now we are ready to enter some data in your router. In order to show you exactly how to configure your router we need you to answer two questions:

Application :
IP Address :

(Make sure the IP address box above contains the static IP address you created in Step 1)

Our router simulator shows you exactly what data to enter in your router based on your choices above. We are currently showing the ports for XBox Live. You should fill out the boxes in the router as you see them here:

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 WRT54GS 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.
