I have docker installed, but only have a vague idea of how it works.

Back in the day, I would just port forward, but even then, I would need a static IP somehow.

I have heard a reverse proxy is an option, but that is an entirely new topic to me.

Surely there is an easy way to access Jellyfin outside of my home network that I'm just missing.

*Edit: I am blown away by all the help and support! I currently have tailscale running, and I'm in the process of purchasing a domain.

Thanks everyone!
