Fastest Buffalo WHR-G125 Router Open Port Instructions

Buffalo WHR-G125 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 WHR-G125 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 WHR-G125 router.

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 Buffalo WHR-G125 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:


192.168.11.1

In the picture above the address bar has 192.168.11.1 in it. Just replace all of that with the IP address of your Buffalo WHR-G125 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: 192.168.11.1

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

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:

From the Group dropdown box select New Group.

Create a name for this forward and put it in the Group Name box. The name is only used as a reminder and has no effect on the port forward.

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

Enable the TCP/UDP radio button.

In the Port Number and LAN Side Port box type the port to forward.

Enter the IP address of the device that you want to forward ports to into the LAN Side IP Address box. This can be either the IP address of your computer or the IP address of another device on your network.

Click the Add button when you are all done.

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