The Asus 4G-AC55U router has a firewall. A firewall blocks all traffic to and from the Internet unless the router considers it safe. To make the router consider certain traffic safe you need to create rules for the router. When you get your router from the manufacturer there are certain rules already in place. However when you want to play certain games online or use online programs you may need to create additional rules. These rules are frequently called port forwarding rules.

In this guide we will show you how to create port forwards for your Asus 4G-AC55U router. We will walk you through the following steps:

  1. How to create a static IP address on the device or game console you are forwarding the ports to.
  2. How to login to the Asus 4G-AC55U router.
  3. How to find the port forwarding section of the router interface.
  4. How to create a port forward entry.

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.

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.

NordVPN birthday deal!

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.

Step 2

It is now time to login to the Asus 4G-AC55U router. To do this you need to use a web browser because these type of routers use a web interface to make setting changes to the device. We recommend using the web browser you feel most comfortable with. Some of the more common browsers are Internet Explorer, Chrome, Firefox, and Edge.

Once you have picked a browser, open it up and locate the address bar. Normally it is at the top of the page 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 4G-AC55U IP Address is:

If the default router IP address did not work or if you know you changed it in the past and don't remember what you changed it to, you need to find out what it is. To do this follow our directions on this How To Find Your Router's IP Address page.

After entering the IP address into the router, press the Enter key on the keyboard and you are shown a login box like this:

Just enter the username and password for the router interface and you are in. Should be easy right? Well...

NOTE: The router username and password are NOT the WiFi username and password.

If the above username and password worked, then congratulations logging in WAS easy.

Can't Login To the Asus 4G-AC55U?

If the default username and password did not work, don't panic. There are a few things you can try:

  • First of all, we recommend trying other Asus username/password combinations. If you have a little different firmware version you could also have a different username and password. Here is our list of Default Asus Router Passwords.
  • Second, did you change the username or password? If you did then enter those values. Don't remember what you changed them to? Use our Find Password App. It will guess thousands of different combinations for you. Learn more about it on this page.
  • Finally, if you have tried both of the above options and still are locked out of the router interface you may need to consider a factory reset. This should be a last resort. A factory reset erases all previously configured settings. Learn the basics of resetting a router on this How to Reset a Router page.

Step 3

If you are reading this, you should be logged in and ready to find the port forwarding section of the Asus 4G-AC55U router. We will be helping you. Let's start on the Network Map page.

Create a name for this forward and put it in the Service Name box. The name is only used as a reminder and has no effect on the port forward.

In the Port Range box enter the ports to forward.

You can ports can be entered as a list 23,24,25, a range 500-600, or a combination of both 23,45,500-600.

Enter the IP address to forward these ports to into the Local IP box. 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.

Use the Protocol dropdown box to select the protocol type of the ports you are forwarding.

Click the + button when you are all done.

That's it, you created new port forward rules for your router. Don't forget to click the Apply button before you leave this page.

Did Your Ports Open Correctly?

There are a few different reasons why a port forward rule doesn't go through correctly. To find out if your port opened properly you need to use an Open Port Checker. We (of course) recommend using our Open Port Checker. Most online port checkers assume that you already have an application (such as your game or torrent) listening for the port test on your computer, and then assume that the test was OK simply because they were able to connect to your computer. Our port checker does not do this. We use a local application to see if the ports are open. With our open port check tool you never get a false positive.

More Information...

If the port forward did not go through you should use our Port Forwarding Software. Everyday we help a lot of people get their port open. Port forwarding should be easy. Our software provides you with everything you need to easily troubleshoot and fix your port forwarding issues.
