Is there any way to prevent clients from changing the DNS servers on their side?
Is there any way to prevent clients from changing the DNS Servers on their side?
CONTEXT:
I am running an AdGuardHome DNS server. All my adblocking and filtering are done in AdGuardHome.
If some "techy" or IT client connects to my network and want to bypass all DNS-level filtering I've configured, then they can just change their DNS servers on their individual devices to any public DNS such as 1.1.1.1.
WHAT I WANT TO ACHIEVE:
I want all traffic will pass through my AdGuardHome DNS server, and whoever changes the DNS servers on their side to anything but my AGH DNS servers will lose internet connection.
Is this possible in the ACLs?
