Asus RT-AC68U Virtual NAS+DDNS (File Sharing) Setup

This virtual NAS helps us out a lot, instead of using cloud storage services like Onedrive and Google Drive, this can let you access your data almost instantaneously on all of your computers at the same time. Like any NASes outside, you can set permissions and it can be accessed by multiple people at the same time! Of course, it supports Windows and OSX.
