    Thanks for the “RTFM” advice. But the manual talks about blocking services from the Internet (ingress). I want to block egress services - processes in the intranet that try to use port 53 outbound.

    The Orbi series of routers dumbs down that level of configuration from users, which makes it challenging to figure it what’s really going on when using the GUI. Instructions on “how to block services from the Internet” need disambiguating from “how to block services to the Internet”.
