CNET CWR-903 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:

  1. Setup a static IP address on either your computer or device that you want to forward a port to.
  2. Login to your CNET CWR-903 router.
  3. Navigate to the port forwarding section.
    • Click the Advanced link.
    • Click on PortForwarding.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your CNET CWR-903 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

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.

With DHCP reservations you can manage your devices from your router. This centralizes the management of your network and helps prevent IP address conflicts. Using this method you do not have to log in to your devices separately.

Step 2

Now we are going to login to your CNET CWR-903 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 CNET CWR-903 IP Address is: 192.168.1.254

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.

Enter your username and password, and then click the Login button to log in to your CNET CWR-903 router.

CNET Usernames and Passwords

If your username and password do not work then please visit our Default CNET Router Passwords page.

If you still can't login to your router because you forgot your CNET CWR-903 router username and password, use our How to Reset a Router Password guide to set your CNET CWR-903 router back to its factory settings.

Step 3

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 link near the left of the page.

You should now see a new menu. In this new menu, click PortForwarding.

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:

If you are forwarding a single port, enter that port number into both of the WAN Port Range and both of the Server Port Range boxes. If you are forwarding a range of ports, enter the lowest number of that range into the left hand WAN Port Range and Server Port Range boxes. Then enter the highest number of that range into the right hand WAN Port Range and Server Port Range boxes.

Enter the IP address that you want to forward these ports to into the Server 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.

The protocol that you want to forward is selected from the Protocol box.

In the Enable checkbox put a checkmark.

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 CNET CWR-903 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.
