Hi y’all, thanks for the help with my question yesterday. I did a bit of homework, and I think I’ve got things figured out. Here’s my revised plan:

  1. configure a cron job to update DuckDNS with my IP address every 5 minutes

  2. use ufw to block all incoming traffic, except to ports 80 and 443, to allow incoming traffic to reach Caddy

  3. configure the Caddyfile to direct traffic from my DuckDNS subdomain to Jellyfin’s port

Does this seem right this time? Am I missing anything, or unnecessarily adding steps? Thanks in advance, I’ll get the hang of all this someday!

What if I want a bunch of people to be able to log into my library via Finamp?

Provide them with VPN access. If that's too much for them, then they don't get access. Tough. On the scale of security vs convenience, that's nothing.

If you really really want, you should at least see if you can put a WAF in front, and put the server itself somewhere it doesn't have access to the rest of your network (a DMZ) so that if and when it gets hacked, it doesn't compromise the entire network.

I highly recommend Tailscale, you can share machines/services with unlimited friends on the free tier, and all of the actual auth stuff is handled by someone who isn't me.

You use plex instead, or you accept the massive security vulnerabilities.

What vulnerabilities? Sure there are some but nothing massive that I have seen. Care to post them.
