Your ZyXEL LTE3311 router has a firewall that it uses to protect your home network from unwanted Internet access. The firewall works by blocking incoming connections. While this is normally a very good thing, some of these connections could help run an online game or application. You can allow additional connections through the firewall. This process of opening ports is typically called a port forward.

In this guide we will be showing you how to port forward on the ZyXEL LTE3311 router. These steps will include:

  1. How to setup a static IP address on the device you are forwarding these ports to.
  2. How to login to the ZyXEL LTE3311 router interface.
  3. How to find the port forwarding section of the device.
  4. How to create a port forward entry on the ZyXEL LTE3311 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.

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.

With DHCP reservations you can manage your devices from your router. This centralizes the management of your network and helps prevent IP address conflicts. Using this method you do not have to log in to your devices separately.

TIP: Write this static IP address down for step 4.

Step 2

It is now time to login to the ZyXEL LTE3311 router. This router uses a web interface which means to login you need to use a web browser. It normally doesn't matter which browser you decide to use, simply pick your favorite such as Chrome, Firefox, or Internet Explorer.

Once you have opened the web browser, find the address bar. If you don't know what this is, it is located at the top of the page 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 LTE3311 IP Address is: 192.168.1.1

After you enter the router's IP address, click the Enter key. This should give you a login page like this:

If a login screen did not appear after you entered the router's IP address in the address bar, you need to find out what the router's IP address has been changed to. I recommend following the directions on the How To Find Your Router's IP Address page.

Go ahead and enter the router's login username and password.

After entering the username and password, go ahead and press the Login button to access the router's user interface.

Having Trouble?

This is a pretty common place to get stuck. If you find yourself here, don't panic, there are a few things you can try:

  • First, check all the different ZyXEL default combinations. Here is our list of all known Default ZyXEL Router Passwords.
  • Second, try and guess what the password/username was changed to. Use our Find Password App to make this step easier.
  • Finally, if you still are stuck after trying both of the above options, it may be time to consider a factory reset. Learn more about this option on the How to Reset a Router page.

Step 3

It is now time to find the port forwarding section of the router. To help you with this step, we begin on the Status page.

First, click the link in the left sidebar that looks like gears. This is the Configuration

Then, click the tab at the top of the page labeled Port Forwarding.

Congratulations, you are now on the correct page to make a port forward entry.

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:

In the Service Name dropdown box pick User-defined.

Put a name for this forward in the Service Name box so that you can remember why you set this forward up. The name does not matter so pick something that has meaning to you.

From the Service Protocol box select the protocol for the ports that you want to forward.

In the WAN Interface dropdown box select an available connection.

If you are forwarding a range of ports then you need to enter the lowest number of that range into the left hand Port Range and Translation Port Range boxes and the highest number of that range into the right hand Port Range and Translation Port Range boxes.

If you are forwarding a single port then you can enter that same port number into both of the Port Range and both of the Translation Port Range boxes.

Enter the IP address that you are forwarding ports to in the Server IP Address box. This is either the IP address of a computer or the IP address of another device on your network.

Click the Add button when you are done.

When you are finished, be sure to save your changes.

Are your the ports you just forwarded really open? An easy way to find out is use our free Open Port Checker. It uses a local application to see if the ports are open or not. This guarantees our port checkers accuracy.
