How to Open Ports in a D-Link DSL-2640T Router

Dlink DSL-2640T 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-2640T 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-2640T 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.

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 guides to setup a static IP address.

After setting up a static ip address on your devices you need to login to your router.

Step 2

Now we are going to login to your Dlink DSL-2640T 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:


10.1.1.1

In the picture above the address bar has 10.1.1.1 in it. Just replace all of that with the IP address of your Dlink DSL-2640T router. Your router's IP address can also be refered to as your computer's default gateway.

By default the IP address is set to: 10.1.1.1

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.

  • The Default D-Link DSL-2640T Router Username is: admin
  • The Default D-Link DSL-2640T Router Password is: admin

Enter your username and password, and then click the Login button to log in to your Dlink DSL-2640T router.

Dlink Usernames and Passwords

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

If you still can't login to your router because you forgot your Dlink DSL-2640T router username and password, use our How to Reset a Router Password guide to set your Dlink DSL-2640T 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:

Dlink DSL-2640T

Click the Advanced link near the top of the page.

The menu on the left should change. In this new menu, click Virtual Server.

Click the Add button near the bottom of the page.

Dlink DSL-2640T port forward

Step 4

Here are the ports to forward for Xbox Live:

TCP Ports:3074
UDP Ports:3074

If you are looking for the ports for a different application you can find it by either:

Create a name for this forward and put it in the Rule Name box. The name is only used as a reminder and has no effect on the port forward.

The protocol that you want to forward is selected from the Protocol box.

If you are only forwarding a single port number then enter that number into both the Port Start, Port Map and the Port End boxes. If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Port Start, Port Map box and the highest number of that range into the Port End box.

When you are done click the Apply button.

Dlink DSL-2640T

Select the applications you just created in the Available Rules list, then click the Add > button to move them to the Applied Rules box.

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

Test if Your Ports are Open

Now that you have forwarded ports on the Dlink DSL-2640T 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.
