Peek first check the request
terminate everything that goes to DoH list wackamole
miss access is when it caches items so do not store login or chat stuff.
splice the splice devices phones etc stuff I can not ssl intecept on and some always splice websites banks etc, bypass intercept list

bump the bump only lists
mark the active use acl true with note directive
terminate anything that does not follow this just in case, I do not think anything ever gets to this acl.

so it is broken up into a dual use set up

ssl_bump peek step1
ssl_bump terminate SSL_Intercept_Terminate
miss_access deny no_miss active_use
ssl_bump splice splice_main active_use
ssl_bump bump bump_main active_use
acl activated note active_use true
ssl_bump terminate !activated

If it's fully standalone in Unbound that should be possible, though I don't know what kind of time frame we'd be looking at.

I haven't kept an eye on it but last I saw it required passing in the https requests from something else like an nginx proxy setup but from the look of those docs they seem to have native support now. The library they mentioned is present on pfSense and is a dependency of Unbound already (the ports option DOH is enabled) so all the backend parts appear to be present, just the GUI/PHP config code would need to be implemented.

The larger problem is that it's going to want to use port 443 which complicates GUI access and makes it trickier to use in practice.
