Cisco RV-120W 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 Cisco RV120W router.
  3. Navigate to the port forwarding section.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Cisco RV-120W 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.

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.

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.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

Step 2

Now we are going to login to your Cisco RV-120W 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 Cisco RV120W 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.

Enter your username and password, and then click the Login button to log in to your Cisco RV-120W router.

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

If you still can't login to your router because you forgot your Cisco RV-120W router username and password, use our How to Reset a Router Password guide to set your Cisco RV-120W 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:

Make up a name to put in the 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.

Select the required protocol for these ports from the Type dropdown box.

If you are forwarding a single port, enter that port number into the Start Port and the Finish Port boxes. If you are forwarding a range of ports, enter the lowest number of that range into the Start Port box. Then enter the highest number of that range into the Finish Port box.

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

Use the Forward from Port dropdown box to choose Same as incoming port.

From the Forward to Port dropdown box select Same as incoming port.

Click the Save 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 Cisco RV-120W 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.
