The most common thing you see is the idea that the holy grail of security being “not forwarding ports in your router”. Put your publicly accessible web service running on your unsegmented home LAN behind a cloudflare tunnel and you’re “secure”, problem solved, job done. If you point out the fact that this doesn’t solve any of the problems that go along with “port forwarding” or that CF tunnels MITMs all their data, you’ll get downvoted as a “CloudFlare hater”.

Similarly they tend to believe that there’s no reason to separate your publicly accessible server from the rest of the devices on your home LAN, especially because the home LAN is “safe”.
