I'll admit I've only really been doing all of this fun self-hosting stuff for about 4 years now but I have been learning computer since Apple II. With my local fiber internet I have a static IP address and seem to have no barriers to expose my hosted websites to the internet. I've never used cloudfare and can't imagine why I would need it. Use NGINX reverse proxy manager at both home and work. Some people have to jump through all these hoops and I'm just curious to know what situations necessitate all the extra hassle.
