I've been dabbling with selfhosting for a bit now (home assistant and nextcloud), but it's clear that I lack a fundamental understanding of networking. For example:

  • I've got OpenWRT on my router, but no idea what I'm doing when it comes to firewall settings, DNS, DHCP, etc.
  • I've got a domain thru Porkbun, but no idea how to properly setup my DNS settings there to route to my local machine.
  • I've got NGINX running in a docker container in a VM and can get to the UI on my local network, but no idea what I'm doing wrong with my attempts at a reverse proxy.

Does anyone here have links to a good in-depth tutorial series for learning about securely selfhosting?

Yup, good notes are really the difference between beginner and expert self-hosters. Write the notes as if they’re documentation to be read by someone who has never seen them before. Don’t tell yourself that you’ll remember things; that is the devil talking. You will forget in 6 months when you’re looking at it again.

that is the devil talking

It truly is. At my age and with other things combined, I can turn around twice in the lab and my brain will flat line.
