So I was able to install everything correctly, but I don’t know what I’m supposed to do in order for people that don’t have my same IP to see my files. I’d like to share my Jellyfin server with some friends so they can see movies there. I’ve already open the ports, but they can’t still access them, I’m using elementaryOS Hera which is built on Ubuntu 18.04.4 LTS.
Yeah maybe I didn’t see that comment (in fact don’t see it still). Unfortunately, you can’t expose a service to others behind a NAT. You can either get a cheap VPS and do some reverse tunneling (the speed with which others load Jellyfin will be limited by your personal upload speed), or get a slightly expensive VPS and host Jellyfin on it.
