How to Port Forward a Comcast CG814WG Router

Your Comcast CG814WG router has a very basic firewall that helps protect your home network from unwanted Internet activity. The firewall does this by blocking incoming and outgoing connections. Some online games and applications run much smoother if you allow additional connections through the firewall. To do this you need to create a port forward.

In this guide we will show you how to properly port forward on the Comcast CG814WG router. These steps include:

  1. How to setup a static IP address on the device you plan on forwarding these ports to.
  2. How to login to the Comcast CG814WG router interface.
  3. How to find the port forwarding page in the router's web interface.
  4. 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!

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.

  • 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.

TIP: Write this static IP address down. You need it in Step 4.

Step 2

Now we are going to login to your Comcast CG814WG 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:


192.168.0.1

In the image above we have circled the address bar for you. In this address bar type in the router's IP address (computer's default gateway).

By default the Comcast CG814WG IP address is set to: 192.168.0.1

After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:

Comcast CG814WG-comcast

You should see a box prompting you for your username and password. If you do not see a login screen you need to find out if the router's IP address has been changed. To do this, follow the instructions on our How To Find Your Router's IP Address page.

  • The Default Comcast CG814WG Router Username is: admin
  • The Default Comcast CG814WG Router Password is: password

Enter your username and password, and then click the Login or OK button to log in to your Comcast CG814WG router.

Comcast Usernames and Passwords

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

Try and guess what the password/username was changed to. Use our Find Password App to make this step easier.

If you still can't login to your router because you forgot your Comcast CG814WG router username and password, use our How to Reset a Router Password guide to set your Comcast CG814WG 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:

Comcast CG814WG-comcast

Begin by clicking the Feature Setup option at the top of the page.

You should see a new menu. Click Port Configuration in this new menu.

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:

Make up a name to put in the Application Name box. The name does not have any effect on the functionality of the forward, it's simply there so you can know why it was created.

If you are just forwarding a single port number then you can simply enter that same number into both the Left Port Range and the Right Port Range boxes. If you are forwarding a range of ports, usually separated by a hyphen, then you need to enter the lowest number of that range into the Left Port Range box and then enter highest number into the Right Port Range box.

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

Enter the IP address of the device that you want to forward ports to into the Server IP box. This can be either the IP address of your computer or the IP address of another device on your network.

Make sure that the Enabled checkbox is checked.

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 Comcast CG814WG 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.
