Your Vtech NB403 router protects your home network by limiting incoming connections from the internet. Sometimes it is necessary to unblock some of those connections like when you want to create a direct connection for gaming, use a specific application, or set up a new device on your network. This process is called forwarding or opening a port. In your Vtech NB403 router you many need to open a port, which means assigning a port number or set of port numbers to a specific IP address. This routes the incoming data to the correct device on your network.
To open ports in your Vtech NB403 router, follow the steps below:
- On the computer or device that you are forwarding ports to, you will need to set up a static IP address.
- Go ahead and log in to your Vtech NB403 router.
- In your Vtech NB403 router, navigate to the Port Forwarding section.
- Find the Advanced tab at the top of the screen and click it.
- Find the Port Forwarding link located near the left of the screen and click on it.
- Create a Port Forwarding entry.
The process of opening ports in your router may seem like a difficult task. If so, you are not alone! We are here to help walk you through the steps to open a port in the Vtech NB403 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 - Setup A Static IP Address
In order to keep the ports in your router open, even after a reboot or disconnect, it is important to set up a static IP address in the device that you are forwarding a port to.
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 - Login To Your Vtech Router
Log in to the Vtech NB403 router. To do this you need to use a web browser because the Vtech NB403 router uses what is called a web interface.
It normally doesn't matter what web browser you use so go ahead and open up your favorite. If you don't have a favorite then open up Chrome, Firefox, or Edge.
If that is confusing to you, we have simplified this step with this link: Login to your NB403 Router
Once you have opened up a browser window, find the address bar. This is usually at the top of the page like the image below shows.
Above is an example of what a web browser address bar looks like. Find the address bar in your web browser and type in your router's IP address.
The default IP address for the Vtech NB403 router is: 192.168.1.1
Once you have entered your router's IP address in the address bar go ahead and click the enter button on your keyboard. You should see a box like the one shown below.
To login, enter the username and password for the Vtech NB403s. Important Note: If you have changed them in the past, you need to enter in those values.
- The default Vtech NB403 Router Username is: admin
- The default Vtech NB403 Router Password is: password
Once you enter your username and password, click the Login button.
Vtech Usernames and Passwords
If the username and password did not work, go to our Default Vtech Router Passwords page for help.
If, after trying the above list of passwords you still can't log in you may need to consider a reset for your router. Learn how to do that by reading our How to Reset a Router guide. **Note:**After resetting the Vtech NB403 router your username and password revert back to factory defaults.
Step 3 - Find The Port Forwarding Section
You should be on the home page of your Vtech NB403 router once you have successfully logged in. Find the Port Forwarding section of your router.
- Find the Advanced tab located near the top of the screen and click it.
- Find the Port Forwarding link located near the left of the screen and click it.
You should now be on a page that says Port Forwarding.
Step 4 - Create A Port Forward Entry
Forwarding ports in your router creates a path that allows data to get through your network firewall, and this could lead to malicious traffic on your network. So make sure that you must forward a port before actually doing so. However, the risk is very low, so do not let this warning stop you from making this change if you need to.
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:
- Browsing our List of Games
- Check out our our List of Games by Genre
- See our List of all Applications
If a template exists for what you're trying to forward you can use the Forward By Template section, but you probably wouldn't be here if one did, so you'll need to do the following in the Custom Forwarding section.
Type in a name for this forward in the Name box. Choose a name that will help you remember why this forward was set up since it does not affect the functionality of the forward.
Choose your internet connection from the Connection drop-down list.
- If you have more than one option and aren't sure which is correct, the Connections page in the Status section of your router may give you an idea.
Click the Add button.
You should now be on a page, that looks something like the following image, where you can enter the port information.
Put a check in the box labeled Enabled.
- You can ignore the Source IP Address / Prefix Length boxes, just leave them set with their defaults.
Enter the IP address that you are forwarding ports to into the Destination IP Address box. It is possible to forward a port to the IP address of your computer or to the IP address of a specific device on your internal network.
In the Protocol dropdown box, select the protocol type of the ports you are forwarding. Choose Both if your router has that option. Otherwise, choose either TCP or UDP as needed. If you need to forward a port for both TCP and UDP and your router does not have the Both option, then you need to create two entries.
Enter the port number into the Forwarded Ports Start and the Forwarded Ports End boxes to forward a single port. If you are forwarding a range of ports, enter the lowest number of that range into the Forwarded Ports Start box and then enter the highest number of that range into the Forwarded Ports End box.
Enter the exact same values that you put in the Forwarded Ports Start box, into the Destination Port Start box.
To finish adding your entry, click on the button that says Apply.
When you are done adding everything, click the Save Settings button at the top of the page when you are completely finished to apply these changes.
