Netcomm NB604N 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 NB604N router.
- Navigate to the port forwarding section.
- Click the Advanced Setup link.
- Click on NAT.
- Click on Virtual Servers.
- Click the Add button.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Netcomm NB604N router.
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 Static IP Setter will set up a static IP address for you.
- Another way to get a permanent IP address is to set up a DHCP reservation.
- Or, manually create a static ip address with our Static IP Guides.
This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.
Now we are going to login to your Netcomm NB604N 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:
Above is an example of what a web browser address bar looks like. Find the address bar in your router and type in your router's IP address.
The default Netcomm NB604N IP Address is: 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 NB604N Router Username is: admin
- The Default Netcomm NB604N Router Password is: admin
Enter your username and password, and then click the Login button to log in to your Netcomm NB604N router.
Netcomm Usernames and Passwords
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 NB604N router username and password, use our How to Reset a Router Password guide to set your Netcomm NB604N 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 Advanced Setup link near the top of the page.
You should now see a new menu. In this new menu, click NAT.
You should now see a new menu. In this new menu, click Virtual Servers.
Click the Add button near the bottom 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:
Put a dot into the Custom Server radio button.
Enter the name of the program into the Custom Server box. It doesn't really matter what you put into this box, but something that will remind you why these ports are being forwarded is be a good idea.
Use the Schedule dropdown box to choose Always.
Enter the IP address that you want to forward these ports to in the Server IP Address box. You can enter either the IP address of your computer or the IP address of another computer or device on your network.
In the Inbound Filter dropdown box select Allow All.
If you are only forwarding a single port then you can enter that same port number into the External Port Start, External Port End, Internal Port Start and Internal Port End boxes. If you are forwarding a range of ports then you need to enter the lowest number of the range into the External Port Start and Internal Port Start boxes and the highest number of the range into the External Port End and Internal Port End boxes.
Select the required protocol for these ports from the Protocol dropdown box.
Click the Apply button when you are done.
Your ports should now be open. It is time to test them.
Test if Your Ports are Open
Now that you have forwarded ports on the Netcomm NB604N 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.
