Tenda D840R 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 Tenda D840R router.
  3. Navigate to the port forwarding section.
    • Click the Virtual Server link.
    • Click the Port Range Forwarding or the Single Port Forwarding button to forward ports.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Tenda D840R 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.

NordVPN is the fastest VPN!

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 Tenda D840R 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:

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

Click the Virtual Server link near the left of the page.

This router has two different sections that allow you to forward ports. One section allows you to forward a range of ports, and the other allows you to forward a single port. To forward a range of ports, click Port Range Forwarding. To forward a single port, click Single Port Forwarding.

Forwarding a Single Port

In the External Port and Internal Port box put the port to forward.

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

Select the protocol type of the ports you are forwarding from the Protocol box.

Verify that you have the Enable checkbox checked.

Forwarding a Port Range

If you are forwarding a single port, enter that port number into the Start Port and the End 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 End Port box.

Enter the IP address that you want to forward these ports to in the To IP Address box. You can enter either the IP address of your computer or the IP address of another computer or device on your network.

From the Protocol box select the protocol for the ports that you want to forward.

In the Enable checkbox put a checkmark.

When you're finished, click Apply near the bottom of the screen to save your changes.

Now that you have forwarded ports on the Tenda D840R 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.
