Thank you very much for your responses.
With iptables, I've noticed that after years of using Gentoo, I've
discovered a multitude of rules whose purposes I no longer remember.
I did a big cleanup and deleted all the rules.
Now I can access my Jellyfin server without any problems.
However, I'm wondering if I might encounter security issues.
What rules would you recommend to avoid problems later on?
