How do I setup DNS over TLS?

You're setting up your Sophos as your local DNS server, and then want to have your Sophos get its answers via DNS over TLS? As far as I know, SFOS doesn't support this yet.

It's on their to-do list. Sophos has their own DNS service which uses standard IP addresses. They need to get DNS-over-TLS support in the firewall, soon, before customers get angry.

But now I suppose the secure DNS that's built into Windows and in most browsers will have to do for now.
