Dlink DSL-520T 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 D-Link DSL-520T router.
  3. Navigate to the port forwarding section.
    • Click the Advanced link.
    • Click on Virtual Server.
    • Click the User radio button.
    • Click the Add button.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Dlink DSL-520T 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 Dlink DSL-520T 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 D-Link DSL-520T 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 Dlink DSL-520T router.

You might notice that most of our site doesn't have ads on it. This is because we use partnerships with companies like NordVPN to keep the site running. Thank you for supporting us by using our referral links.

Make up a name to put in the Rule 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.

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

If you are only forwarding a single port then you can enter that same port number into the Port Start, Port End, Port Map and Port Map End boxes. If you are forwarding a range of ports then you need to enter the lowest number of the range into the Port Start and Port Map boxes and the highest number of the range into the Port End and Port Map End boxes.

Click the Apply 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 Dlink DSL-520T 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.
