How to Forward Ports in a Netcomm NB5540 Router

Netcomm NB5540 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 NB5540 router.
  3. Navigate to the port forwarding section.
    • Click the 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 NB5540 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 NB5540 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 NB5540 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 NB5540

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

  • The Default Netcomm NB5540 Router Username is: blank
  • The Default Netcomm NB5540 Router Password is: admin

Enter your username and password, and then click the Login button to log in to your Netcomm NB5540 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 NB5540 router username and password, use our How to Reset a Router Password guide to set your Netcomm NB5540 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 NB5540

Click the Port Forwarding link near the left 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:

Put a name for this forward in the Application 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.

Enter the same port number to be forwarded into both the Ext.Port and the Int. Port boxes.

Select the protocol type using the Protocol radio button. If you need both TCP and UDP then create a duplicate configuration.

The first configuration needs to have TCP selected while the second one has UDP selected.

You need to enter the IP address that you are forwarding ports to in the IP Address box. It's possible for this to be either the IP address of your computer or any other IP address on your network that you want ports forwarded to.

Make sure that the Enable checkbox is checked.

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 NB5540 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.
