Your DSL-2740U router helps to protect your network by blocking incoming internet connections. This is an important feature that helps you to control which applications have access to your network. Sometimes you want to allow network access to a specific application in order to play a game, connect a device, or use an app. The D-Link DSL-2740U can unblock certain incoming connections through port forwarding or by opening a port. You can open ports in your DSL-2740U by assigning specific ports to an IP address. Forwarding these ports directs incoming data to a specific device or application.
To open a port in your D-Link DSL-2740U router, follow these important steps:
- Set up a static IP address on the device or computer you are forwarding these ports to.
- Go ahead and log in to your D-Link DSL-2740U router.
- Find the Port Forwarding section in your D-Link DSL-2740U router.
- Click on the Advanced tab, which is at the top of the screen.
- Find the Port Forwarding tab at the left of the screen and click it.
- Create a Port Forwarding entry.
The process of opening ports in your D-Link DSL-2740U router may seem daunting. Remember, however, that you are not alone and do not have to feel discouraged. Let us walk you through the steps for opening ports in your router. Let's get this figured out!
Setup A Static IP Address
It is important to set up 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.

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 your D-Link DSL-2740U router. To log in you will need to use a web browser since the D-Link DSL-2740U uses a web interface to access router configurations.
Open up whichever internet browser that you are comfortable with. If you are not sure which one to use, then go ahead and open Chrome, Firefox, or Edge.

Once you have opened a web browser, find the address bar which is usually located at the top of the screen. The image below shows an example of this.
Above is an example of what a web browser address bar looks like. Find the address bar in your web browser and type in your router's IP address.
The default IP address for the D-Link DSL-2740U router is: 192.168.1.1
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.
Enter the username and password for the D-Link DSL-2740U in the corresponding boxes. Important Note: If you have changed them in the past, you need to enter in those values.
- The default D-Link DSL-2740U Router Username is: admin
- The default D-Link DSL-2740U Router Password is: admin
To log in to your D-Link DSL-2740U router, enter your username and password, and then click the Log In button.
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-2740U 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
After successfully logging in to your D-Link DSL-2740U router you should see the router's home page on your screen. Find the Port Forwarding section of your router.
- Click on the Advanced tab, which is at the top of the screen.
- Find the Port Forwarding tab located near the left of the screen and click on 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 this could lead to malicious traffic on your network. So make sure that you must 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:
Click on the radio button called User-defined Service Name.
Put a name for this forward in the User-defined Service 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.
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.
Don't worry about the WAN Setting option, you can leave it on Interface.
Select any from the WAN Interface drop-down box.
The WAN Port box accepts either a single number or a range of numbers. If you are forwarding a single port number then enter that port number into the WAN Port box. If you are forwarding a range of ports such as 1000-2000 then you can enter the lowest number of that range into the WAN Port box, followed by a colon, followed by the largest number. An example would look like this: 1000:2000.
Enter the same values into the LAN Open Port box that you entered into the WAN Port box.
Find the LAN IP Address box and enter the IP address that you want ports forwarded to. This can be either the IP address of your computer or any other IP address for devices on your network that you want to forward ports for.
Make sure to click the Add button at the bottom of the page to apply these changes, when you are completely finished.
