you still need good security configuration of the exposed service.
In a sense that security comes in layers, yes. But in practice, this setup will prevent 100% of bots scanning the internet for exposed services, and absolute majority of possible targeted attacks as well. It’s like using any other 3rd party VPN, except there’s not a central point for the traffic to flow through.
From the attackers point of view, nothing is listening there.
I’ve used a similar setup in the past to access a device behind a NAT (possibly multiple NATs) and a dynamic IPv4. Looking back, that ISP was a pure nightmare.
