Opening Ports on the Netgear CG3000

The Netgear CG3000 router includes a basic firewall that helps protect your local network from all unwanted Internet access. A firewall does this by blocking all incoming and outgoing traffic from the Internet unless the router allows it. The only way your router will allow more traffic through the firewall is if you create a port forward rule allowing traffic to flow through the port or ports you specified to a particular computer on your home network.

In this guide we will cover all the steps in order to get your ports forwarded on the Netgear CG3000 router. We will show you exactly how to:

  • Setup a static IP address on the exact device you are forwarding these ports to.
  • Login to the Netgear CG3000 router.
  • Find the port forwarding section of the Netgear CG3000 router.
  • Create the port forward entry.

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 guide to setup a static IP address.

TIP: It's a good idea to write this static IP address down. You will need it again in Step 4.

Step 2

In order to login to the Netgear CG3000 router you need to open a web browser because your router uses a web interface. The web browser can be Chrome, Internet Explorer, Edge, or Firefox. It should not matter which browser you decide to use.

After you open the web browser, find the address bar. This is normally at the top of the page like this:

Netgear CG3000 address-bar-circled

The address bar has been circled for you with in it.

Replace what is in the bar with the Netgear CG3000 router's IP address. This can also be called the router's GUI address or the computer's default gateway.

By default the Netgear CG3000 router has an IP address of:

Once you have entered the router's IP address into the address bar, simply press Enter.

If the correct IP address was used you will see a login screen screen similar to this:

If you are not shown the above screen, something went wrong. At this point you need to find out what the router's IP address was changed to. In order to do this follow the instructions on our How To Find Your Router's IP Address page.

You should see a box prompting you for your username and password.

  • The Default Netgear CG3000 Router Username is: admin
  • The Default Netgear CG3000 Router Password is: password

Enter your username and password, and then click the OK button to log in to your Netgear CG3000 router.

Having Trouble?

This is a very common place to get stuck. Here are a few things you can try:

  • We first recommend trying other Netgear username/password combinations. It is possible you have a different version than this. Different versions sometimes have different passwords. Here is our list of Default Netgear Router Passwords.

  • The most common reason a password won't work is because you have changed it in the past. You can do a couple things here: First, you can try guessing what you changed it to. Second you can use our Router Password Cracker to do the guessing for you. This handy tool really does make owning a router a lot easier.

  • The last thing you can try is a factory reset. Do not attempt a factory reset unless you have exhausted all your other troubleshooting options. To learn the basics of a reset read this How to Reset a Router page.
Step 3

Congratulations on logging into the Netgear CG3000 router. Now let's find the port forwarding section of the device. To help you do this we start on the Basic Settings.

Click the Port Forwarding link on the left side of the page.

You are now on the correct page of the router to make a port forward.

Step 4

You can now start to enter the port forwarding information. To help you with this step we need a little more information from you:

Application :
IP Address :

(Do you remember the Static IP address you setup in the first step? Enter that address in the IP address box above.)

This next section we call the router simulator. It mimics the Netgear CG3000 router port forward boxes. All you need to do is copy what is in the boxes below into your router. Currently we are showing the ports for XBox Live.

And that is it! You are done!

Don't Forget to Test Your Ports

After you have finished all of the above steps, you need to see if the Netgear CG3000 router forwarded them without any problems. To do this we recommend using our Network Utilities tool, which includes a free Open Port Checker. Our port checker uses a local application to listen for the server trying to connect and then positively verifies that your ports are forwarded.
