Thank you.
To your point, one example that comes to mind is that I have read many people complaining about cloudflare, saying it’s “evil” and over extending. While I agree on the aspect of Cloudflare being sort of a monopoly, I am not sure what else to use to route some of my traffic to my services running at home without explicitly opening up ports to the internet by using a reverse proxy for example.
In that regard, Cloudflare has access to my traffic and data could theoretically leak that way, but I am not sure what is a safer and better alternative to it.
I used the IP + MAC address of the devices I want to block.
