Linksys WAG120N 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:
- Setup a static IP address on either your computer or device that you want to forward a port to.
- Login to your Linksys WAG120N router.
- Navigate to the port forwarding section.
- Click the Applications & Gaming link.
- Click on Single Port Forwarding or Port Range Forwarding.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Linksys WAG120N router.
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. Download Network Utilities today!
- Another highly recommended way of getting a permanent IP address is to set up a DHCP Reservation.
- Or, follow our Static IP Address Setup guides.
With DHCP reservations you can manage your devices from your router. This centralizes the management of your network and helps prevent IP address conflicts. Using this method you do not have to log in to your devices separately.
Now we are going to login to your Linksys WAG120N 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:
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 Linksys WAG120N IP Address is: 192.168.1.1

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:
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.
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 Single Port
Put a name for this forward in the Application box so that you can remember why you set this forward up. The name does not matter so pick something that has meaning to you.
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 of the device that you want to forward ports to into the IP Address box. This can be either the IP address of your computer or the IP address of another device on your network.
Make sure that the Enable checkbox is checked.
Forwarding a Port Range
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.
If you are forwarding a single port, enter that port number into the Port Range Start and the Port Range End boxes. If you are forwarding a range of ports, enter the lowest number of that range into the Port Range Start box. Then enter the highest number of that range into the Port Range End box.
In the Protocol box select the protocol that you want to forward these ports over.
Enter the IP address that you want to forward these ports to in the IP Address box. You can enter either the IP address of your computer or the IP address of another computer or device on your network.
Put a checkmark in the Enable checkbox.
When you're finished, click Save Settings near the bottom of the screen to save your changes.
