Asus RT-AC1900P Router Open Port Guide

The Asus RT-AC1900P routers include a very basic firewall that helps protect your home network from unwanted access from the Internet. Since this firewall blocks incoming connections you may need to 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 the device you are forwarding these ports to.
2. Login to your Asus RT-AC1900P router.
3. Navigate to the port forwarding section.
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-AC1900P 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 Static IP Setter will set up a static IP address for you.
• Another way to get a permanent IP address is to set up a DHCP reservation.
• Or, manually create a static ip address with our Static IP Guides.

This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

TIP: Write this static IP address down for later.

Step 2

Now we can login to the Asus RT-AC1900P router. This router has a web interface which means you need to login using a web browser. It doesn't usually matter which browser you decide to use, I recommend using one you are familiar with such as Chrome, Internet Explorer, or Firefox.

Open up your web browser and find the address bar. It should look something like this:

Above is an example of what a web browser address bar looks like. Find the address bar in your router and type in your router's IP address.

The default Asus RT-AC1900P IP Address is: 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. If you do not see a login screen like the one above, you need to find out what the router's IP address has been changed to. Follow the directions on the How To Find Your Router's IP Address page.

• The Default Asus RT-AC1900P Router Username is: admin
• The Default Asus RT-AC1900P Router Password is: password

Enter your username and password, and then click the blue Sign In button to log in to your Asus RT-AC1900P router.

Asus Usernames and Passwords

If your username and password do not work then please visit our Default Asus Router Passwords page to try other common Asus defaults.

Use our Find Password App to help you figure out what the router's username and password have been changed to.

Finally, if you still can't access your router, use our How to Reset a Router Password guide to set your Asus RT-AC1900P router back to its factory settings, then try the default values again.

Step 3

Now we need to find the port forwarding section in your router. Here's how you do it. Starting from the Home Network Map page in your router:

On this page click the WAN link in the left sidebar.

Then, click the Virtual Server/Port Forwarding link at the top of the page.

You are now on the correct page to make a port forward entry.

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:

• Browsing our List of Games
• Check out our our List of Games by Genre
• See our List of all Applications

Don't forget to sign up for NordVPN's promo deal before it's gone.

You need to name this entry in the Service 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.

Type the port to forward into the Port Range box.

Enter the IP address that you want to forward these ports to into the Local IP box. Note that if you are forwarding ports so you can run a program on a device other than your computer then you can enter your device's IP address into that box instead.

Select the required protocol for these ports from the Protocol dropdown box.

Click the Add button when you are done.

Make sure to click the Apply button when you are done.

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

Test if Your Ports are Open

Now that you have forwarded ports on the Asus RT-AC1900P 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.
