I don’t like opening ports on my home router, because of the destination services behind the port forwarding. As long as those are secure there are no problems. But if a service has a vulnerability, someone could takeover my home network and creep around. That’s scary.
When people use Cloudflare Tunnels to publish their stuff, they usually still have that problem. The idea is that Cloudflare is intrinsically safe and would block all attacks. I don’t necessarily agree with that. But I assume it’s safer than having no security layer between at all.
Yes, I agree. Security wise I also don’t see a benefit in hosting the reverse proxy externally. I believe a dynamic DNS provider with a low TTL for the DNS records should work as good or perhaps even better. Not better security wise, but simpler setup, more reliable.
