Do you actually understand what is port forwarding? Like every other router, Asus RT-AC88U routers also feature a basic firewall setting that protects your home network from unwanted or unauthorized access through the Internet. A firewall is an application that restricts every incoming connection from the web door.
Since the firewall blocks every incoming connection, there is a need to open a port for allowing games and other application connections. This process of opening a port for giving access to such useful applications is referred to as port forwarding. This process is frequently so-called as a port forward since you are forwarding a port from the internet to your home network.
Step 1 : Set a static IP address on your computer system or device that you want to forward a port to.
Step 2 : Log in to the admin interface of Asus RT-AC88U router.
Step 3 : Go to the port forwarding section of the interface.
Step 4 : Click the WAN option
Step 5 : Select the Virtual Server/Port Forwarding option.
