My case (here the rDNS problem):
server hostname: server.domain.tld
panel: server.domain.tld
rDNS: server.domain.tld
A-Record on cloudflare: server.domain.tld -> orange cloud
Now i want to set with your command as follow:
A-Record on cloudflare: login.domain.tld -> orange cloud
A-Record on cloudflare: server.domain.tld -> change to grey cloud
change the panel hostname with your command: login.domain.tld
So the hostname and rDNS matches again. And only the panel is handled with the proxied cloudflare record?
This works?
