What does the tunnel bring except DoS protection and hiding your IP? And what is the security concern with divulging your IP? Say when I connect to a website, the website knows my IP and I don't consider this a security risk.

If I run vulnerable software, it will still be vulnerable through a Cloudflare tunnel, right?

Genuinely interested, I'm always scared to expose things to the internet :-).

Small "except". :)

With the amount of automated bots that port scan looking for anything/everything that's open, as well as scanning DNS records for server IPs that could be targeted, one of the nice patterns of cloud hosting is how application and data servers are hosted behind firewalls of some kind, to effectively be internal.

As for what's exposed to the web, let's say the payload of a website, if there was something vulnerable in the javascript, that could be a weakness hosted anywhere.

Cloudflare can also help achieve this without too much fuss for self-hosted projects, be it personal, and production grade, assuming the rest of the trimmings are tehre.

		> one of the nice patterns of cloud hosting is how application and data servers are hosted behind firewalls of some kind Oh I see, so that I benefit from the "professional" firewall of Cloudflare, as opposed to my own that I may have possibly misconfigured or forgot to update etc? Or is there more, like Cloudflare will block IPs that know to come from malicious actors and things like this?
