Router's Parental Controls Really Block All Internet Traffics?

RRN asked:

I am using Asus 4G-AC53U router. When I turn ON “Parental Controls” to block a client’s Internet access, does the router really block ALL kinds of Internet traffics including system’s service (such as OS update checking, license checking, etc.) ? Or it only block normal user’s access, e.g. web browsing, video streaming, etc.?

My answer:


This small office/home router has a function named “parental control” which is actually a simple time-of-day restriction for devices. During the times of day that you configure, the specified device cannot access anything on the network at all.
