How to Forward Ports in a D-Link DFL-1100 Firewall Router

Dlink DFL-1100 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 DFL-1100 Firewall router.
  3. Navigate to the port forwarding section.
    • Click the Firewall button.
    • Click the Port Mapping link.
    • Click the Add new link.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Dlink DFL-1100 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 DFL-1100 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:


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 Dlink DFL-1100 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: 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:

Dlink DFL-1100

You should see a box prompting you for your username and password.

  • The Default D-Link DFL-1100 Firewall Router Username is: admin
  • The Default D-Link DFL-1100 Firewall Router Password is: admin

Enter your username and password, and then click the Login button to log in to your Dlink DFL-1100 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 DFL-1100 router username and password, use our How to Reset a Router Password guide to set your Dlink DFL-1100 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 DFL-1100

Click the Firewall button near the top of the page.

Click the Port Mapping link near the left of the page.

Click the Add new link.

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:

You need to name this entry in the Name box. The name does not make any difference in the forward; it's just there so that you can remember later why you setup this forward.

The Source Nets: box cab be left empty.

You can leave the Users/Groups: box empty.

Go ahead and leave the Destination IP: box empty.

In the Service box select the protocol that you want to forward these ports over.

You can leave the Custom source ports: box empty.

In the destination ports: box enter the ports to forward.

You can ports can be entered as a list 23,24,25, a range 500-600, or a combination of both 23,45,500-600.

You can leave the pass to ports: box empty.

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

Use the Schedule dropdown box to select Always.

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 DFL-1100 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.
