I have a client which uses our applications hosted with url (example *.myurl.com and *.myurl.dev)
So, in order to allow them to access those services behind Cloudflare I have Firewall access rules which acts as a whitelist. This whitelist includes all the IP addresses of our client. So whenever they add up a new service or IP address, they request to allow a new IP address.
But there is a new application which would need me to allow FQDN instead of IP address.
In CFL access rules I can see IP address, Subnets, ASNs can be allowed. I would like to allow their FQDN (example src.IP eq xyz.com) name which would
- remove the overhead of managing IP addresses.
- Allow New application
- Allow our client more flexibility.
How can I achieve that.
