Please stop exposing your NAS to the internet (do this instead)

Your NAS is often the place where you store all your most important files. Backups, photos, movies, and so on—there’s a reason why all that stuff isn’t just rotting on your PC and is instead being actively kept safe. But there’s an easy way to sabotage all that security, and it comes down to port-forwarding your NAS to the public internet.
