Fastest D-Link DSR-250 Router Port Forwarding Guide

A D-Link DSR-250 router protects your home network by blocking unwanted incoming internet connections and acting as a basic firewall. Sometimes you need to open a port in your router in order to get a good connection for a game or to use a specific device on your network. The DSR-250 lets you choose the applications that are allowed to connect through an open port. By opening a port in your router you allow a specific application or game to send data from the internet to your home network.

The following steps will show you how to open ports on the D-Link DSR-250 router:

  1. Set up a static IP address on the computer or device that you are forwarding ports to.
  2. Login to your D-Link DSR-250 router.
  3. Find the Custom Services section in your D-Link DSR-250 router.
    • Find the Security tab at the top of the screen and click on it.
    • Click on Custom Services.
  4. Create a Custom Services entry.
  5. Navigate to the Firewall Rules section in your D-Link DSR-250 router.
    • Find the Security tab at the top of the screen and click on it.
    • Click Firewall Rules.
  6. Go ahead and create a Firewall Rules entry.

If this sounds difficult you are not alone. We will walk you through each step in opening a port for the D-Link DSR-250 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 - Setup A Static IP Address

In order to keep the ports in your router open, even after a reboot or disconnect, it is important to set up a static IP address in the device that you are forwarding a port to.

  • Recommended - Our free program will setup a static IP address for you.

    → Download Network Utilities today!

  • 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 - Login To Your D-Link Router

The D-Link DSR-250 router uses a web interface to display router settings. In order to login to the D-Link DSR-250 router you need to use a web browser.

Open your favorite web browser. If you don't have a favorite or are not sure what this means, open up Chrome, Firefox, or Internet Explorer. If you are already in a browser window, go ahead and open up a new tab.

We have simplified this step for you with this link: Login to your DSR-250 Router

Find the address bar in your browser window. This is usually found at the top of the page, like in the image below.

In the above screenshot, you should see an address bar with in it. This is your router's IP address (sometimes called the computer's default gateway.)

The default IP address for the D-Link DSR-250 router is:

Once you have entered your router's IP address in the address bar go ahead and click the enter button on your keyboard. You should see a box like the one shown below.


Go ahead and enter the username and password for the D-Link DSR-250 router in the spaces available. Remember if you have changed them in the past, you need to enter those values.

  • The default D-Link DSR-250 Router Username is: admin
  • The default D-Link DSR-250 Router Password is: admin

Enter your username and password, and then click the Login button to log in to your D-Link DSR-250 router.

D-Link Usernames and Passwords

If the username and password did not work, go to our Default D-Link Router Passwords page for help.

If, after trying the above list of passwords you still can't log in you may need to consider a reset for your router. Learn how to do that by reading our How to Reset a Router guide. **Note:**After resetting the D-Link DSR-250 router your username and password revert back to factory defaults.

Step 3 - Find The Custom Services Section

You should be on the home page of your D-Link DSR-250 router once you have successfully logged in. Find the Custom Services section of your router.


  • Find the Security tab located near the top of the screen and click it.
  • Click Custom Services.

You should now be on a page that says Custom Services.


Step 4 - Create a Custom Service

Opening a port to a specific device may solve problems that you are having on your network. Make sure that it is necessary though, before opening a port, because you are effectively creating a pinhole in the firewall portion of your router that could lead to malicious traffic on your network. The risk is exceedingly low though, so don't let this warning stop you from making this change if you need it.

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:


  1. Click on the Add New Custom Service button.

  2. Put a name for this forward in the Name box so that you can remember why you set this forward up. The name does not matter so pick something that has meaning to you.

  3. Use the Type dropdown box to select the protocol type of the ports you are forwarding. If your router has the option of Both then choose that. Otherwise select either TCP or UDP as needed. If you need to forward a port for both TCP and UDP and your router does not have Both then you have to create two entries.

  4. Put a dot in to the Port Range or Multiple Ports radio button.

  • Select the Port Range option to forward a Single or Range of ports.

To forward a single port, enter the port number into the Source Start Port and the Source Finish Port boxes. To forward a range of ports, enter the lowest number in the range into the Source Start Port box. Then enter the highest number in the range into the Source Finish Port box.

Then go ahead and take the values that you entered in the Source Port boxes and put the exact same numbers in the Destination Port boxes.

  • Select the Multiple Ports option to forward a List of ports.

Enter the list of ports you want to forward, separated by a comma, in to both the Source Ports and the Destination Ports boxes. An example would like something like: 1000,2000-3000,4000

  1. When you're done filling things out, click on the button labeled Save.

Step 5 - Navigate to the Firewall Rules Section

Now that you've created your Custom Services, you'll need to allow them through the Firewall. Go ahead and head over to the Firewall Rules section now.

  • Click on the Security tab, which can be found at the top of the screen.
  • Click Firewall Rules.

You should now be on a page that says Firewall Rules.


Step 6 - Create a Firewall Rules Entry

You should be by default, but if you're not then make sure you're on the IPv4 Firewall Rules tab.


  1. Click on the Add New IPv4 Firewall Rule button.

  2. Choose INSECURE (WAN) from the From Zone dropdown box. If you have more than one WAN option, you'll need to pick the one that applies to your internet connection.

  3. Choose SECURE (LAN) from the To Zone drop down list.

  4. Select the custom service you created in earlier from the Service dropdown menu.

  5. For the Source Hosts, click on the radio button that says Any.

  6. For the Destination Hosts, click on the Single Address radio button. Then, go ahead and enter the IP address that you are forwarding ports to into the Destination Hosts box. It is possible for this to be either the IP address of your computer or of any other device on your network that you want ports forwarded to.

  7. Whether you want to Log things or not is up to you, but typically most leave this on Never.

  8. The QoS Priority is also up to you, but Normal-Service is suitable for most.

  9. After you've finished configuring things here, click the Save button.

Test If Your Ports Are Open

Finally, I strongly recommend testing to see if you forwarded the D-Link DSR-250 ports correctly. To do this you can use our Network Utilities tool, which includes a free Open Port Checker. Open Port Checker is the only online port checking tool that has Guaranteed Results.
