Easiest Way to Get an Open Port on the ZyXEL P 660RT2 Router

ZyXEL P660RT2 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 P 660RT2 router.
3. Navigate to the port forwarding section.
   • Click the Network link.
   • Click on NAT.
   • Click the Port Forwarding button.
   • Select User Define in the drop down.
   • Click the Add 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 P660RT2 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.

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 Static IP Setter will set up a static IP address for you.
• Another way to get a permanent IP address is to set up a DHCP reservation.
• Or, manually create a static ip address with our Static IP Guides.

This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

Step 2

Now we are going to login to your ZyXEL P660RT2 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 660RT2 IP Address is: 192.168.1.1

If you are looking for the ports for a different application you can find it by either:

• Browsing our List of Games
• Check out our our List of Games by Genre
• See our List of all Applications

Don't forget to sign up for NordVPN's promo deal before it's gone.

Make sure that the Active checkbox is checked.

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

If you are forwarding a single port, enter that port number into the External Port Start, External Port end, Internal Port Start and Internal Port End boxes. If you are forwarding a range of ports, enter the lowest number of the range into the External Port Start and Internal Port Start boxes. Then enter the highest number of the range into the External Port end and Internal Port End boxes.

Enter the IP address that you want to forward these ports to in the Server 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 are finished, click the Apply button.

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