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)

    One thing that people dont get is what firewall actually does - It blocks

    • no open ports - cant get in, solid wall everywhere
    • open ports - as if you put doors somewhere in the wall, depending on doors quality they can get in easily or not at all

    That minecraft is a good example. You open port to it, people can join it, but depending on how you setup your minecraft server, if it has plugins that require registration and password to move around, well that either stop people from griefing or not.
