Fastest D-Link DSL-124 Router Open Port Instructions

A D-Link DSL-124 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 DSL-124 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.

To open a port in your D-Link DSL-124 router, follow these important steps:

  1. On the computer or device that you are forwarding ports to, you will need to set up a static IP address.
  2. Go ahead and log in to your D-Link DSL-124 router.
  3. Navigate to the Port Forwarding section in your D-Link DSL-124 router.
    • Find the Advanced tab located near the top of the screen and click on it.
    • Find the Port Forwarding tab located near the left of the screen and click on it.
  4. Go ahead and create a Port Forwarding entry.

If this sounds difficult you are not alone. We will walk you through each step in opening a port for the D-Link DSL-124 router.

Setup A Static IP Address

Set up a static IP address in the device that you are forwarding a port to. This is an important step that keeps your ports open even after a reboot, power outage, or other type of device or router disconnect.

  • 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.

Login To Your D-Link Router

Log in to the D-Link DSL-124 router. To do this you need to use a web browser because the D-Link DSL-124 router uses what is called a web interface.

It normally doesn't matter what web browser you use so go ahead and open up your favorite. If you don't have a favorite or are confused, open up Chrome, Firefox, or Internet Explorer.

If that is confusing to you, we have simplified this step with this link: Login to your DSL-124 Router

Once you have opened up a browser window, find the address bar. This is usually at the top of the page like the image below shows.

You should see in the address bar of the screenshot shown above. This is your router's IP address (sometimes listed as the default gateway.)

The D-Link DSL-124 router's default IP address is:

Once you have finished entering your router's IP address into the address bar, click the enter button on your keyboard. A box similar to the one below should appear.

Basic Authentication

Enter the username and password for your D-Link DSL-124 router. Note: If you have changed these numbers in the past, you will need to enter in the those values.

  • The default D-Link DSL-124 Router Username is: admin
  • The default D-Link DSL-124 Router Password is: admin

Once you have entered your username and password, remember to click the Log In button to login to your D-Link DSL-124 router.

D-Link Username and Password Trouble

If the username and password that you typed in did not work, check out our Default D-Link Router Passwords page for other ideas about possible passwords.

If, after trying the above list of passwords you still can't log in, you may need to reset your router. Learn how to do that by reading our How to Reset a Router guide. After resetting the D-Link DSL-124 router your username and password are reverted back to factory defaults. Router settings may also change when you reset, so make a note of your current router settings before you reset.

Find the Port Forwarding Section

You should be on your routers home page once you complete logging in. Find the Port Forwarding section on the home page of the D-Link DSL-124 router.


  • Find the Advanced tab at the top of the screen and click on it.
  • Find the Port Forwarding tab located near the left of the screen and click it.

You should now be on a page that says Port Forwarding.

Create A Port Forward

Forwarding ports in your router creates a path that allows data to get through your network firewall and it is possible that this could lead to malicious traffic on your network. So make sure that it is really necessary for you to forward a port before actually doing so. However, the risk is very low, so do not let this warning stop you from making this change if you need to.

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 radio button labeled User-defined Service Name. Then, create a name for this forward and type it into the User-defined Service Name box. Since the name does not have an effect on the functionality of the forward, choose a name that will help you remember why the forward was created.

  2. Select the protocol type of the ports that you are forwarding from the Protocol dropdown box. If your router has the option of Both, then go ahead and select that. Otherwise select either TCP or UDP as needed. If you need to forward a port for both TCP and UDP but your router does not have Both, then you will need to create two entries.

  3. Choose any from the WAN Interface dropdown box.

  4. To forward a single port, enter the port number into the WAN Port box. To forward a range of ports, enter the entire range, separated by a colon, into the WAN Port box. An example of a port range would look something like: 1000:2000

  5. In the LAN Open Port box, enter the same values that you entered into the WAN Port box.

  6. Enter the IP address that you are forwarding ports to into the LAN IP Address box. It is possible to forward a port to the IP address of your computer or to the IP address of a specific device on your internal network.

  7. When you are completely finished, click the Add button at the bottom of the page to apply these changes.
