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?

They probably couldn't. But, at the end of the day, the risk is yours to take. Nothing is 100% secure; it's all about degrees of security vs usability. You seem to have taken a reasonable approach to protecting the web service, so that's a good start. Other things would be to ensure that access is logged, and that failed attempts are delayed between retries (preventing brute forcing to be completed in a reasonable time) - not sure if Synology has that or not.
