How to Port Forward a Buffalo WZR-HP-AG300H DD-WRT Router

Buffalo WZR-HP-AG300H_DD-WRT_v24SP2-MULTI 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 WZR-HP-AG300H DD-WRT router.
  3. Navigate to the port forwarding section.
    • Click the NAT / QoS link.
    • Click the Port Range Forwarding or the Port Forwarding button to forward ports.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Buffalo WZR-HP-AG300H_DD-WRT_v24SP2-MULTI 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 WZR-HP-AG300H_DD-WRT_v24SP2-MULTI 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 WZR-HP-AG300H_DD-WRT_v24SP2-MULTI 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:

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 Single Port

Click the Add button.

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.

Use the Protocol dropdown box to select the protocol type of the ports you are forwarding.

Enter the port to forward into both the Port From and the Port To boxes.

You need to enter the IP address that you are forwarding ports to in the IP Address box. It's possible for this to be either the IP address of your computer or any other IP address on your network that you want ports forwarded to.

Make sure that the Enable checkbox is checked.

Forwarding a Port Range

Click the Add button.

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.

If you are just forwarding a single port number then you can simply enter that same number into both the Start and the 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 Start box and then enter highest number into the End box.

The protocol that you want to forward is selected from the Protocol box.

You need to enter the IP address that you are forwarding ports to in the IP Address box. It's possible for this to be either the IP address of your computer or any other IP address on your network that you want ports forwarded to.

Verify that you have the Enable checkbox checked.

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