ZyXEL Prestige660HW-T3 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 Prestige 660HW T3 router.
  3. Navigate to the port forwarding section.
    • Click the Advanced Setup link.
    • Click on NAT.
    • Click Edit Details.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your ZyXEL Prestige660HW-T3 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.

Get Started Now!

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.

  • 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 Prestige660HW-T3 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:


10.0.0.138

In the picture above the address bar has 10.0.0.138 in it. Just replace all of that with the IP address of your ZyXEL Prestige660HW-T3 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: 10.0.0.138

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

ZyXEL Prestige660HW-T3

You should see a box prompting you for your username and password.

  • The Default ZyXEL Prestige 660HW T3 Router Username is: admin
  • The Default ZyXEL Prestige 660HW T3 Router Password is: 1234

Enter your username and password, and then click the Login button to log in to your ZyXEL Prestige660HW-T3 router.

ZyXEL Usernames and Passwords

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

If you still can't login to your router because you forgot your ZyXEL Prestige660HW-T3 router username and password, use our How to Reset a Router Password guide to set your ZyXEL Prestige660HW-T3 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:

ZyXEL Prestige660HW-T3

Click the Advanced Setup link near the left of the page.

You should now see a new menu. In this new menu, click NAT.

ZyXEL Prestige660HW-T3

There should be a dot in the SUA Only setting. If this isn't the case, you can not setup port forwarding without making a major change to your network. I wouldn't advise changing this unless you know what you are doing. Alright, if there is a dot in the SUA Only setting, go ahead and click Edit Details.

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:

Verify that you have the Active checkbox checked.

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

Try entering 10.0.0.138 into the Start IP and End IP box. The numbers 10.0.0.138 stand for any assigned IP address. When you enter that number it means whatever external IP address has been assigned to my router. If that does not work you have to enter your external IP address manually. This may be a problem because your external IP address can change. When it changes these ports will not be forwarded properly.

If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Start Port No. box and the highest number of that range into the End Port No. box. If you are only forwarding a single port number then enter that number into both the Start Port No. and the End Port No. boxes.

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.

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

Test if Your Ports are Open

Now that you have forwarded ports on the ZyXEL Prestige660HW-T3 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.
