ZyXEL P-336M 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 336M router.
- Navigate to the port forwarding section.
- Click the Advanced link.
- Click on Game Hosting.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your ZyXEL P-336M 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.
- 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.
Now we are going to login to your ZyXEL P-336M 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 336M IP Address is: 192.168.2.1
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 336M Router Username is: admin
- The Default ZyXEL P 336M Router Password is: 1234
Enter your username and password, and then click the Login button to log in to your ZyXEL P-336M 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 P-336M router username and password, use our How to Reset a Router Password guide to set your ZyXEL P-336M 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 Advanced link near the left of the page.
You should now see a new menu. In this new menu, click Game Hosting.
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 Enable checkbox checked.
Create a name for this forward and put it in the Name box. The name is only used as a reminder and has no effect on the port forward.
Enter the IP address that you want to forward these ports to into the IP Address box. Note that 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 instead.
Enter the ports to forward into the TCP Ports to Open or UDP Ports to Open box.
The ports can be entered as a list 23,24,25, a range 500-600, or a combination of both 23,45,500-600.
These entries are protocol specific. If the ports you are forwarding need to be forwarded using the TCP protocol, you should enter those ports into the TCP section. If the ports you are forwarding need to be forwarded with the UDP protocol, you should enter those ports into the udp section.
Pick Allow All from the Inbound Filter dropdown box.
Use the Schedule dropdown box to choose Apply Always.
When you are done click the Save button.
When you're finished, click Save Settings near the top of the screen to save your changes.
