Fastest Tilgin NB403 Router Port Forwarding Instructions

Your Tilgin NB403 router uses a firewall to help protect your home network from unwanted Internet activity. The firewall works by blocking incoming traffic that you may need opened for a better online experience. The process of opening additional ports is called a port forward because you are forwarding a port through the firewall.

In this guide I will show you how to port forward on the Tilgin NB403 router. This process is broken down into four steps:

  1. How to setup a static IP address on the device you plan on forwarding these ports to.
  2. How to login to the Tilgin NB403 router web interface.
  3. How to find the port forwarding page in the router's web interface.
  4. How to setup a port forward for the online game or program of your choice.

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.

TIP: Write this static IP address down. You need it in Step 4.

Step 2

It is now time to login to the Tilgin NB403 router. Your router uses a web interface which means you need to use a web browser to login. It normally doesn't matter which browser you decide to use, simply pick your favorite such as Chrome, Internet Explorer, or Firefox.

Once you have opened the web browser, find the address bar. This is normally at the top of the page like this:

I have circled the address bar for you in red, all you need to do is replace what is currently in the address bar with the router's IP address. The router's IP address is also called the computer's default gateway.

The default IP address for the Tilgin NB403 router is:

Now press the Enter key. If everything goes right you should see a login screen similar to this:

Tilgin NB403 Login

If you don't see a login screen similar to the one above, you need to find out what the current IP address is for the router. To do that we have a How To Find Your Router's IP Address guide to help you.

Go ahead and enter the router's username and password on this page.

  • The Default Tilgin NB403 Router Username is: admin
  • The Default Tilgin NB403 Router Password is: password

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 Tilgin default combinations. Here is our list of all known Default Tilgin 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 interface. We begin on the Status Summary page.

Tilgin NB403 Home

On this page you click the option of Advanced at the top of the page.

Tilgin NB403 UPnP

This takes you to a new page like the one above. Click the option in the left sidebar labeled Port Forwarding.

You should now see a page like the one above. Scroll down to the section that says Custom Forwarding. Then enter the name of the program you are forwarding in the box that says Name. It really doesn't matter what you enter here, we recommend entering something that will help you remember why you forwarded this port.

Now enter the Static IP address you created in Step 1 in the box that says Connection.

Finally click the option of Add.

Tilgin NB403 Port Forwarding Edit

You will now see a page similar to the one above. It may read Add custom port forwarding rule instead of "edit".

This is the correct page to be on in order 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:

Use the Protocol dropdown box to select the protocol type of the ports you are forwarding.

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

Test Your Ports

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.
