ZyXEL P660HW-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:
- Setup a static IP address on either your computer or device that you want to forward a port to.
- Login to your ZyXEL P 660HW T3 router.
- Navigate to the port forwarding section.
- Click the NAT link.
- Click Edit Details.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your ZyXEL P660HW-T3 router.
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.

- Or, follow our Static IP Address Setup guides.
After setting up a static ip address on your devices you need to login to your router.
Now we are going to login to your ZyXEL P660HW-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:
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 ZyXEL P 660HW T3 IP Address is: 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 P 660HW T3 Router Username is: 1234
- The Default ZyXEL P 660HW T3 Router Password is: 1234
Enter your username and password, and then click the Login button to log in to your ZyXEL P660HW-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 P660HW-T3 router username and password, use our How to Reset a Router Password guide to set your ZyXEL P660HW-T3 router back to its factory settings.
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:
Click the NAT link near the center of the page.
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.
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:
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. 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.
Enter the IP address to forward these ports to into the 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'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 P660HW-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.
