Buffalo WCR-GN 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 Buffalo WCR-GN router.
  3. Navigate to the port forwarding section.
    • Click the LAN Config button.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Buffalo WCR-GN 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.

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 Buffalo WCR-GN 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 Buffalo WCR-GN IP Address is: 192.168.11.1

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.

Enter your username and password, and then click the Login button to log in to your Buffalo WCR-GN router.

Buffalo Usernames and Passwords

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

If you still can't login to your router because you forgot your Buffalo WCR-GN router username and password, use our How to Reset a Router Password guide to set your Buffalo WCR-GN 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:

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:

In the Group dropdown box select New Group.

Make up a name to put in the Group 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.

From the Internet Side IP Address dropdown box choose AirStation's Internet IP Address.

Enable the TCP/UDP radio button.

Enter the port to forward into the Port Number and LAN Side Port box.

Enter the IP address that you want to forward these ports to into the LAN Side 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.

After you are done click the Add button.

Your ports should now be open. It is time to test them.

Test if Your Ports are Open

Now that you have forwarded ports on the Buffalo WCR-GN 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.
