Would be useful from a user perspective to have these displayed in the GUI and allow user to choose there own. Not a fan predefined DNS and NTP.
The user ultimatedly should be able to configure key service NTP/DNS.
If you hve hardwired services please show these in the GUI , allow user to choose there preffered services.
The fact the user is not aware of the https proxy is not a good thing,
Can’t think of a router apart from ISP locked down one, where NTP and DNS are forced / locked down or hidden from from the user.
