Fastest Way to Forward Ports on the Asus RT-N15U Router

Asus RT-N15U 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 Asus RT-N15U router.
  3. Navigate to the port forwarding section.
    • Click the WAN button.
    • Click on Virtual Server / Port Forwarding.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Asus RT-N15U router.

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 Asus RT-N15U 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 Asus RT-N15U 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:

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

  • The Default Asus RT-N15U Router Username is: admin
  • The Default Asus RT-N15U Router Password is: admin

Enter your username and password, and then click the Login button to log in to your Asus RT-N15U router.

If you still can't login to your router because you forgot your Asus RT-N15U router username and password, use our How to Reset a Router Password guide to set your Asus RT-N15U 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:

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:

Put a dot into the Enable Port Forwarding Yes radio button.

Put a name for this forward in the 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.

If you are forwarding a range of ports, enter the port range into the Port Range box. The lowest port in the range should be entered first, then a dash, and then the highest port in the range. For example, you can enter 500-600 to forward all ports between 500 and 600.

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

If you are forwarding a range of ports, enter the port range into the Local Port box. The lowest port in the range should be entered first, then a dash, and then the highest port in the range. For example, you can enter 500-600 to forward all ports between 500 and 600.

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

Click the Add button when you are finished.

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