ZyXEL P-661H-D1 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 661H D1 router.
- 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.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your ZyXEL P-661H-D1 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.

- TCP Ports: 3074
- UDP Ports: 3074
If you are looking for the ports for a different application you can find it by either:
In the Active checkbox put a checkmark.
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 Start Port and the End Port boxes. If you are forwarding a range of ports, enter the lowest number of that range into the Start Port box. Then enter the highest number of that range into the End Port box.
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.
Click the Apply button when you are done.
When you're finished, click Apply near the bottom of the screen to save your changes.
