Like, I hear all the time that you shouldn't open any ports on your networks fire wall for security reasons this and security reasons that. But what are the actual security implications/risks of forwarding a port for something like Jellyfin or a Minecraft server or something like that? Explain like im 16 (or something)

If you're confident to expose a machine on a VPS and you can manage the implications then you can manage a machine in a DMZ of your NAT/Firewall home router.

If the server it's a bare metal UNIX than you're ok (i.e. *BSD || *Linux on a Raspberry Pi 4/5) , the basic install it's better than Fort Knox
