Netcomm NB3300 Router Port Forwarding
Netcomm NB3300 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:
- Setup a static IP address on either your computer or device that you want to forward a port to.
- Login to your Netcomm NB3300 router.
- Navigate to the port forwarding section.
- Click the Virtual Server link.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Netcomm NB3300 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!
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.

Now we are going to login to your Netcomm NB3300 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:
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 NB3300 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:
You should see a box prompting you for your username and password.
- The Default Netcomm NB3300 Router Username is: blank
- The Default Netcomm NB3300 Router Password is: admin
Enter your username and password, and then click the Login button to log in to your Netcomm NB3300 router.

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 NB3300 router username and password, use our How to Reset a Router Password guide to set your Netcomm NB3300 router back to its factory settings.
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:
Click the Virtual Server link near the left of the page.
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:
If you are forwarding a single port, enter that port number into the Left Incoming Ports and the Right Incoming Ports boxes. If you are forwarding a range of ports, enter the lowest number of that range into the Left Incoming Ports box. Then enter the highest number of that range into the Right Incoming Ports box.
From the Incoming Ports box select the protocol for the ports that you want to forward.
Enter the IP address that you want to forward these ports to into the Redirect IP Address box. Note that if you are forwarding ports so you can run a program on a device other than your computer then you can enter your device's IP address into that box instead.
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 NB3300 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.
