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)

    A lot of great and valuable replies here so far. I’ll add my comments anyway.

    I have learned over the years of selfhosting/homelabbing and being an IT professional that as u/emprahsFury stated,

    Oftentimes though people don’t know what they don’t know, and we only find out that we don’t know after we’ve moved from the prevention phase to the remediation phase.

    I have seen this for years professionally. Unless you think like the bad guy, you don’t know what the bad guy is thinking. Not knowing what the bad guy is thinking does not mean that the techniques and possibilities do not exist.

    Taking some time to learn what the bad guys can do can be very helpful to the self-hoster in general.
