I am looking for a gui friendly interface to do parental control functions as lack of literacy in command line utility.
Came accross this- OAF (open app filter)
It does block websites via domain, and if for example someone found a bypass by using a different dns you could hijack all dns traffic and point to your own server like this example:
I'm not sure if adguard has this feature, but i do know that the firewall has it, meaning you can disable all internet from some ips, or a network in a certain time.
