Enhanced DynDNS Management and Control within Firewall Manager

It would be highly beneficial to have the capability to allow or block addresses at the DynDNS level within the Firewall Manager. This feature would provide administrators with finer control over access by dynamic IP addresses, directly within the user interface, improving ease of use and response time to IP changes.

Furthermore, it would be advantageous to enable SMTP authentication restrictions based on DynDNS within the Firewall Manager. Specifically, this would allow administrators to grant or restrict SMTP authentication for specific DynDNS entries, enhancing security and operational control by aligning email access permissions with dynamically changing IPs.
