Opening a Port on the Motorola NVG510

On this page I will explain how to port forward the Motorola NVG510 router.

Your Motorola NVG510 router contains a very basic firewall that helps to protect your home network from unwanted outside access. By design a firewall blocks connections from the Internet. It sometimes becomes necessary to unblock some of these connections whether for a game or other application. This process of unblocking a connection is called port forwarding. A port forward literally opens a port allowing traffic to come and go through that port as quickly as possible to a device on your home network.

The basic process to open a port is:

  1. Setup a static ip address on the game console or device you want these ports forwarded to.
  2. Login to your Motorola NVG510 router.
  3. Find the port forwarding section.
    • Click the Firewall link.
    • Click on NAT/Gaming.
  4. Create a port forward entry.

Don't worry if these steps seem difficult, we will walk you through each and every step in the process in order to forward your ports for the Motorola NVG510 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.

  • Or follow our Static IP Address guide to setup a static IP address.

Step 2

Step two involves logging into your Motorola NVG510 router. Your router takes advantage of a web interface. This means in order for you to login to your router you need to open a web browser. It doesn't matter which browser you use just pick a favorite. Some of the more common web browsers are Edge, Firefox, Safari, and Chrome.

Once you have opened the web browser of your choice, find the address bar. This address bar is typically found at the top of the page.

In the image above the address bar has the numbers in it. All you need to do is enter the router's IP Address in place of whatever is in the address bar when you open it.

If you are having trouble finding out what your router's IP Address is, remember a router IP Address can also be referred to as the computer's default gateway.

By default the Motorola NVG510 router IP Address is:

You are on the right track if you are now being asked for a username and password.

  • There is NO default Motorola NVG510 router username.
  • There is NO default Motorola NVG510 router password.

Unless you have changed these values in the past, just leave them blank and click the OK button to login to the Motorola NVG510 router.

Motorola Usernames and Passwords

If the username and password combination did not work, then we recommend a visit to our Default Motorola Router Passwords page to try some other common Motorola usernames and passwords.

If you are still unable to login to the Motorola NVG510 router it is probably because you changed them in the past and have forgotten. It might be time to consider a router reset. Don't do this unless you are sure you don't know the username and password and have done some looking. To learn more about resetting the router check out our How to Reset a Router guide.

Step 3

After a successful login to the Motorola NVG510 router you need to find the port forwarding section. To help you with this step, start on the following page:

In the blue bar at the top of the page click the link labeled Firewall.

At this point a new menu appears underneath, click the NAT/Gaming option.

Step 4

Alright, you made it to the port forwarding page. In order for us to show you what information to enter in your router you need to answer the following 2 questions:

Application :
IP Address :

(The IP Address above needs to match the static IP Address you setup earlier.)

The next box or boxes show you exactly what data to enter in your router. We are currently showing the ports for XBox Live. All you need to do is fill in the boxes on your router exactly as you see them below.

And that is it! You are done!

Test if Your Ports are Open

Once you have finished forwarding those ports on the Motorola NVG510 router you should test them to see if they forwarded correctly. We recommend using our Network Utilities tool, which includes a free Open Port Checker. Our Open Port Checker is the only one online with Guaranteed Results, never giving you a false positive.
