Can someone please explain to me, a casual home user, why it's dangerous to expose my NAS login page to the internet?... (alien.top)

...without snark or jumping down my throat. I genuinely want to know why it's so unsafe.

I'm running a Synology DS920+, with my DSM login exposed through a Cloudflare tunnel. I have 2FA enabled, Synology firewall enabled with these rules in place. I also have this IP blocklist enabled.

After all of this, how would someone be able to break in via the DSM login?

All software has bugs. Sometimes bugs let you do things you weren't intended to be able to do (e.g. access data on a NAS without knowing the login password). Your NAS might have a bug that hasn't been discovered (or publicized yet) or hasn't been fixed yet.

If you put your NAS on the internet, you give "bad guys" am opportunity to exploit those bugs to get your data or to use your NAS as a jumping off spot to attack other things inside your home network.
