Title: Is it possible to block/forward dns requests of clients not using port 53?
Post by: EdwinKM on March 02, 2022, 07:57:39 PM
I am not talking about DoT and DoH but plain vanilla  unencrypted DNS requests but just using another port.

Is a list of known internet dns servers the only solution/workaround? (which it is for HTTPS) of can the firewall somehow detect that a DNS query is made?
