Netcomm nb1 Router Open Port Guide

Netcomm nb1 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 Netcomm nb1 router.
  3. Navigate to the port forwarding section.
    • Click the Advanced button.
    • Click the Port Forwarding link.
    • Click the Custom Port Forwarding link.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Netcomm nb1 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.

  • Recommended - Our free program will setup a static IP address for you.
  • Or follow our Static IP Address guides to setup a static IP address.

After setting up a static ip address on your devices you need to login to your router.

Step 2

Now we are going to login to your Netcomm nb1 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:


192.168.1.1

In the picture above the address bar has 192.168.1.1 in it. Just replace all of that with the IP address of your Netcomm nb1 router. Your router's IP address can also be refered to as your computer's default gateway.

By default the IP address is set to: 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:

Netcomm nb1

You should see a box prompting you for your username and password.

  • The Default Netcomm nb1 Router Username is: admin
  • The Default Netcomm nb1 Router Password is: admin

Enter your username and password, and then click the Login button to log in to your Netcomm nb1 router.

Netcomm Usernames and Passwords

If your username and password do not work then please visit our Default Netcomm Router Passwords page.

If you still can't login to your router because you forgot your Netcomm nb1 router username and password, use our How to Reset a Router Password guide to set your Netcomm nb1 router back to its factory settings.

Step 3

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:

Netcomm nb1

Click the Advanced button near the top of the page.

Netcomm nb1

Click the Port Forwarding link near the left of the page.

Netcomm nb1

Click the Custom Port Forwarding link near the right of the page.

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 Connection dropdown box choose an available connection.

Put a checkmark in the Enable checkbox.

You need to name this entry in the Application box. The name does not make any difference in the forward; it's just there so that you can remember later why you setup this forward.

Select the required protocol for these ports from the Protocol dropdown box.

Try entering 192.168.1.1 into the Source IP Address box. The numbers 192.168.1.1 stand for any assigned IP address. When you enter that number it means whatever external IP address has been assigned to my router. If that does not work you have to enter your external IP address manually. This may be a problem because your external IP address can change. When it changes these ports will not be forwarded properly.

In the Source Netmask box put 192.168.1.1.

Enter the IP address of the device that you want to forward ports to into the Destination IP Address box. This can be either the IP address of your computer or the IP address of another device on your network.

Verify that Destination Netmask is set to 192.168.1.1.

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

Click the Apply button when you are finished.

Select the applications you just created in the Available Rules list, then click the Add > button to move them to the Applied Rules box.

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

Test if Your Ports are Open

Now that you have forwarded ports on the Netcomm nb1 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.
