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.
Also, log in to your Jellyfin server. Go to Settings > Admin Dashboard > Networking and tick the checkbox for “Allow remote connections to this server”.
Done.
Did you also untick ‘Enable automatic port mapping’?
Yup.
