Your RT-AC66R 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 Asus RT-AC66R can unblock certain incoming connections through port forwarding or by opening a port. You can open ports in your RT-AC66R by assigning specific ports to an IP address. Forwarding these ports directs incoming data to a specific device or application.
Follow these steps to open a port in your Asus RT-AC66R router:
- Set up a static IP address on the computer or device that you are forwarding ports to.
- Go ahead and log in to your Asus RT-AC66R router.
- Make your way to the Virtual Server / Port Forwarding section of the Asus RT-AC66R router.
- Find the WAN tab located near the left of the screen and click it.
- Find the Virtual Server / Port Forwarding tab located near the top of the screen and click on it.
- Go ahead and create a Virtual Server / Port Forwarding entry.
If this sounds difficult, you are not alone. We will walk you through each step in opening a port for the Asus RT-AC66R 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 - 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 another type of device or router disconnect.

After setting up a static ip address on your devices you need to login to your router.
Step 2 - Login To Your Asus Router
The Asus RT-AC66R router uses a web interface to display router settings. In order to login to the Asus RT-AC66R router you need to use a web browser.
Open your favorite web browser. If you don't have a favorite or are not sure what this means, open up Chrome, Firefox, or Edge. If you are already in a browser window, go ahead and open up a new tab.
We have simplified this step for you with this link: Login to your RT-AC66R Router
Find the address bar in your browser window. This is usually found at the top of the page, like in the image below.
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 Asus RT-AC66R router's default IP address is: 192.168.1.1
After typing your router's IP address into the address bar, make sure to click the enter button on your keyboard. You should see a box similar to the one shown below.
Enter the username and password for your Asus RT-AC66R router. Note: If you have changed these numbers in the past, you will need to enter in the those values.
- The default Asus RT-AC66R Router Username is: admin
- The default Asus RT-AC66R Router Password is: admin
Once you have entered your username and password, remember to click the Sign In button to login to your Asus RT-AC66R router.
Asus Usernames and Passwords
If the username or password did not work check out our Default Asus Router Passwords page.
If you are unable to log in even after trying the above list of passwords you may need to consider a reset for your router. Our guide How to Reset a Router can help you with that. After resetting the Asus RT-AC66R router your username and password will be reverted back to factory defaults.
Step 3 - Find The Port Forwarding Section
You should be on your routers home page once you complete logging in. Find the Virtual Server / Port Forwarding section on the home page of the Asus RT-AC66R router.
- Click the WAN tab at the left of the screen.
- Click the Virtual Server / Port Forwarding tab at the top of the screen.
You should now be on a page called Virtual Server / Port Forwarding.
Step 4 - Create A Port Forward Entry
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.

- Click on the Add Profile button. You should now see a screen that looks like this:
-
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. Or leave it blank if you want, it's up to you.
-
In the Protocol dropdown box, select the protocol type of the ports you are forwarding. Choose Both if your router has that option. Otherwise, choose either TCP or UDP as needed. If you need to forward a port for both TCP and UDP and your router does not have the Both option, then you need to create two entries.
-
Enter the ports you want to forward in to the External Port box. You can enter a single port number, a range of port numbers separated by a colon, or a list containing both separated by commas. An example of a list would look something like this: 1000,2000:3000,4000.
- The Internal Port box is optional. It can, and in most cases should be left empty. By default it uses the same information that was entered in to the External Port box.
-
In the Internal IP Address box, enter the IP address that you want ports forwarded to. This may be the IP address of your computer or the IP address of another device on your network that you want to forward ports to.
- The Source IP box is also optional, and in most cases should also be left blank. If you understand its purpose and wish to make use of it don't let us stop you, but if you don't then just leave it empty.
-
Click the OK button at the bottom of the page when you are completely finished to apply these changes.

Finally, test your network to see if you have forwarded ports in the Asus RT-AC66R router correctly. To do this you can use Network Utilities, which includes a free Open Port Checker tool. Open Port Checker is the only online port-checking tool that has Guaranteed Results.
