Your guide sounds obviously written by an LLM. I think that's okay, and you might have directed the LLM's work, but don't say you wrote it; this misrepresents the guide as more carefully crafted and authoritative than it really is.
Do you see an advantage or alternative benefits to also having a public dynamic DNS, because for me I am struggling to see any?
It would be nice to get something like that also with easy TLS setup.
