Netgear WNDR3700 Open Port Guide

The Netgear WNDR3700 router includes a very basic firewall that helps protect your home network from 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.

In this guide we will walk you through each of the steps in port forwarding the Netgear WNDR3700 router. These steps are:

  • How to setup a static IP address on the device you want to forward these ports to.
  • How to login to the Netgear WNDR3700 router.
  • How to find the port forwarding section of the router.
  • How to make a 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.

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.


NOTE: Write this address down. You need it for Step 4.

Step 2

It is time to login to the Netgear WNDR3700 router. To do this you need to open up a web browser. It typically doesn't matter which browser you decide to use. I recommend picking the one you are most familiar with. Some common web browsers are Chrome, Internet Explorer, Edge, and Firefox.

Open the web browser and find the address bar. This will normally be at the top of the page like this:


192.168.1.1

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 Netgear WNDR3700 router. Your router's ip address can also be refered to as your computer's default gateway.



The default Netgear WNDR3700 IP address is: 192.168.1.1



After entering the router's IP address into the address bar, click the Enter key on the keyboard and you are shown the following image:

If the above login page does not appear, you need to find out what the router's IP address has been changed to. To help you with 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 WNDR3700 Router Username is: admin
  • The Default Netgear WNDR3700 Router Password is: password


Enter your username and password, and then click the OK button to login to your Netgear WNDR3700 router.

Netgear Usernames and Passwords

This is a common place to get stuck. Here are three things you can do:

  • Try other Netgear passwords. If you have a slightly different firmware version you could easily have a different username and password combination. Her is our list of different Default Netgear Router Passwords.

  • How about using our Router Password Cracker. It finds the password for you.

  • If you are still unable to access the router's interface you may need to consider a factory reset. A factory reset erases all the previously configured settings. This is not advisable unless you have no other options. Learn the basics of resetting a router on this How to Reset a Router page.
Step 3

This third step is how to find the port forwarding section of the router. To do that we will begin on the first page of the Netgear WNDR3700 router.

Look in the left sidebar and click the option of Port forwarding / Port Triggering.

On this new screen, make sure the Port Forwarding radio button is selected.

Then click the button labeled Add Custom Services.

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

Step 4

In this step we will be entering the port forwarding data into your router. In order for us to show you exactly how to configure your router we need a little more information:

Application :
IP Address :

(The IP address box above is referring to the static IP address you created in the first step.)

After filling in the above two boxes you can scroll down to our router simulator. It simulates the boxes on the port forwarding page in your Netgear WNDR3700 router. Currently we are showing the ports for XBox Live. If this is accurate, simply fill in the boxes in your router exactly as you see them below.

When you are finished with each entry, click the Apply button to save your work.

And that is it! You are done!


Test if Your Ports are Open

Now that you have forwarded ports on the Netgear WNDR3700 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.
