Easiest Way to Forward Ports on the ZyXEL NBG-334W Router

ZyXEL NBG334W 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 ZyXEL NBG-334W router.
  3. Navigate to the port forwarding section.
    • Click the Network link.
    • Click on NAT.
    • Click the Application button.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your ZyXEL NBG334W 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 ZyXEL NBG334W 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:


192.168.1.1

In the picture above the address bar has 192.168.1.1 in it. Just replace all of that with the IP address of your ZyXEL NBG334W 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: 192.168.1.1

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.

  • The Default ZyXEL NBG-334W Router Password is: 1234

Enter your username and password, and then click the Login button to log in to your ZyXEL NBG334W router.

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:

Make sure that the Active checkbox is checked.

Put a name for this forward in the Service Name 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.

In the Port box put the ports to forward.

These ports can be entered as a list 23,24,25, a range 500-600, or a combination of both 23,45,500-600.

Enter the IP address to forward these ports to into the Server IP Address box. 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.

When you are done click the Apply 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 ZyXEL NBG334W 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.
