    OK maybe this is not the end? So firefox and Google Chrome have this ECH (Encrypted Client Hello) and you can test here

    https://tls-ech.dev/

    But in Wireshark you still see that domain name Client Hello? So maybe I miss the point about ECH or they overlooked this and if so Zyxel can still Content Filter HTTPS.

    Hi @PeterUK,

    Thanks for reporting this question. We will check with UTM team to see if content filter is working or not with the Encrypted Client Hello.
