In case you are interested how I solved having a publicly signed SSL certificate for a home server not connected to the Internet, here is what I did:

codeberg.org/harald/Codeschnip

The downside: there seems to be no way without having a registered domain. It took me unnecessary time to accept this. The upside: taking the step to get yourself a domain is simpler and cheaper than I was aware of and with the right tool, the rest was easy enough.

I started a discussion with fellow #sysadmin about updating #BIND / #named config to migrate from the overly permissive allow-update {…} stanzas to the more restricted update-policy {…} stanzas using targeted grant statements.

The idea being to allow the #acme client to only be able to update (add / delete) _acme-challenge TXT instead of any record in the zone.

Old:

allow-update {
TSIG_KEY_NAME;
};

New:

update-policy {
grant TSIG_KEY_NAME name _acme-challenge.example.net TXT;
};
