The page rules are basic, one redirects to an Etsy shop, another to serve images for email from a cdn, and another for handling QR codes.
Tunnels are set up for subdomains to reach internal network stuff, with a Cloudflare Zero Trust login which prompts for those that don’t have secure logins.
The DNS stuff is subdomains, email records, and a few records for certain game servers.
I also use cloudflare to monitor my DKIM rejections, though my email is through mxroute as they have/had a lifetime option and I don’t like subscriptions.
There are a few different sites as well, one is personal, one is for public facing stuff, a couple for side businesses.
It’s honestly just easier to keep as much together as possible.
