I guess I didn’t explain properly, or maybe I don’t get it.
If I enable the proxy (brown cloud), I know that people using Cloudflare as their DNS (i.e. the public) will get proxied through Cloudflare.
But if my client is using a private internal DNS to point auth.aaapv.com to my web server, will people using his DNS (i.e. on his internal network) get proxied? Won’t they bypass the proxy and go directly to my server?
How can he configure his internal DNS to send his users through the proxy?
