Synology RT1900ac Router Port Forwarding

Your Synology RT1900ac router has a basic firewall that helps to protect your home network from unwanted Internet access both to and from the Internet. Your firewall does this by blocking ports except a few in order for you to use the Internet. When you need additional ports opened for a game or program this is called a port forward because you are forwarding a port through the firewall to a device on your network.

In this guide we will walk you through each step in the process of port forwarding. These include:

  • How to setup a static IP address on the exact device you plan on forwarding these ports to.
  • How to login to the Synology RT1900ac router.
  • How to find the port forwarding section of your router.
  • Finally, we will be showing you what information to enter in your router to get your ports forwarded.

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 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

When you want to login to the Synology RT1900ac router you need know that a router like this uses a web interface. This means you need to use a web browser to get into the router settings. It shouldn't matter which browser you decide to use, simply pick your favorite. Some common web browser options are: Chrome, Internet Explorer, Edge, and Firefox.

Once you have picked the web browser you want to use, open it up and find the address bar. This is normally at the top of the page like this:

Do you see the address bar at the top of the page in the image above? We have circled it for you in red. All you need to do is replace what is in this bar with your router's IP address. (The router IP address is also sometimes called the Default Gateway.)

NOTE: If you have changed the router's IP address in the past then you need to enter that value. If you don't remember what you changed it to, then you can follow the directions on our How To Find Your Router's IP Address page.

The default IP address for the Synology RT1900ac router is:

Now that you have entered the router's IP address into the address bar, click the Enter key on your keyboard. If everything went according to plan you should see the following screen:

Synology RT1900ac login

On this login screen you need to enter a username and password. According to my research you set a password during the initial setup of the Synology RT1900ac router. There is no default username and password for this device.

Having Trouble?

Hopefully you wrote down the username and password you created during the initial router setup. If you did not, there are still some things you can try:

  • Our first recommendation is to try and crack your own router password. What are some common password choices you tend to use? If you want some brute force behind your guessing you can use our Find Password App. It automates the process of trying thousands of different username/password combinations to get your router accessible to you. Learn all about this helpful app on our Router Password Cracker page.
  • If trying to guess your password did not work it might be time to consider a reset. The manual for the Synology RT1900ac router calls it a soft reset. A reset like this will erase not only your username and password but will erase other settings such as the firewall , DHCP services, Wi-Fi, Parental Control, and Traffic Control. To do this you press and hold the reset button on the bottom of the router for about 4 seconds. We strongly suggest trying other methods first before deciding to reset this device. For more information on resetting a router check out this How to Reset a Router page.

Step 3

After you have finished logging into the Synology RT1900ac router you need to find the port forwarding section of the menu. To do this we begin on the Home page:

Synology RT1900ac home

Click the file labeled Network Center. In the screenshot above it is near the upper left corner.

Synology RT1900ac port forward

To get to the page you see above, you need to:

  • Click the Internet option in the left sidebar.
  • Then choose the option at the top of the page labeled Port Forwarding
  • A new sub-menu appears, pick the option of Create

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 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.

Enter the IP address of the device that you want to forward ports to into the Private IP Address box. This can be either the IP address of your computer or the IP address of another device on your network.

Enter the port to forward into the Public Port and the Private Port boxes.

The protocol that you want to forward is selected from the Protocol box.

When you are finished, click the Create button.

Don't forget to click the Create button after you complete each port forward entry.

When you are completely finished, click the option near the top of the page labeled Save.

Test Your Ports

It is a great idea to test the ports you just forwarded. In order to do this we recommend using our Open Port Checker. This is part of our FREE trial version of the Network Utilities. Our Open Port Checker is a great tool that uses a local application to see if your ports are listening or not.
