The context of this entire discussion is connecting to internal services; the kind you wouldn’t have in your DMZ, as that has no privileged access to your network.

Anyhoo, you do you, but I certainly wouldn’t make public a reverse proxy with access to my internals.

I think you might be drastically misunderstanding what a reverse proxy does.

Reverse proxy: Gives EVERY computer a direct connection to your network if you make it public, which it certainly sounds like you mean.

VPN: gives only you access to your internals.
