Simple Vtech NB403 Router Port Forwarding Guide
Your router has a very basic firewall that helps keep your home network safe from unwanted Internet activity. The Vtech NB403 firewall works by blocking incoming and outgoing connections that have not been opened by your router. Some online games or programs run much better if you open additional connections through your router's firewall. This process is normally called a port forward.
Each router forwards ports just a little bit differently. In this guide I will show you how to port forward on the Vtech NB403 router. The steps I will be covering are:
- How to setup a static IP address on the device you plan on forwarding these ports to.
- How to login to the Vtech NB403 router web interface.
- How to find the port forwarding page in the router's web interface.
- 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!
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.
- → Download Network Utilities today!
- 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.
It is now time to login to the Vtech NB403 router. This router uses a web interface which means you need to open up a web browser in order to login to the router's user interface. It normally doesn't matter which browser you decide to choose, simply pick your favorite such as Chrome, Internet Explorer, Edge, or Firefox.
Once you have opened the web browser up, find the address bar. This is normally at the top of the web page like this:
In the image displayed above I have circled the address bar for you. You need to enter the router's IP address in this space. The router's IP address is also called the computer's default gateway.
By default the Vtech NB403 router has an IP address of: 192.168.1.1
After entering the router's IP address press the Enter button. If everything goes well you will see a login page like this:
The login section is in the upper right corner of the page. If you don't get a page like this one, you should find out if the router's IP address has been changed. To do this follow the directions on our How To Find Your Router's IP Address page.
Go ahead and enter the router login username and password and press the Login button to access the rest of the router's user interface.
- The Default Vtech NB403 Router Username is: admin
- The Default Vtech NB403 Router Password is: password
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 Vtech default combinations. Here is our list of all known Default Vtech 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 are still 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.
Now we need to find the port forwarding section of the Vtech NB403 router. To help you with this step we will begin on the Home page:
First, click the option at the top of the page labeled ADVANCED.
Now click the option in the left sidebar labeled Port Forwarding.
On this page, click the Add button under the Custom Forwarding section.
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:
Select the protocol type of the ports you are forwarding from the Protocol box.
If you are only forwarding a single port then you can enter that same port number into the Forwarded ports Start, Forwarded ports End, Destination ports Start and Destination ports End boxes. If you are forwarding a range of ports then you need to enter the lowest number of the range into the Forwarded ports Start and Destination ports Start boxes and the highest number of the range into the Forwarded ports End and Destination ports End boxes.
Don't forget to save your changes before you exit.
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.
