Pfsense dynamic dns not updating
Under Windows NT, DNS was static and had to be manually altered to make changes.With the advent of Windows 2000, many administrators were elated to hear that it contained a new feature called Dynamic DNS (DDNS).And why is the successful registration reported as failed? For custom Dyn DNS services, the server's response to the update request is compared to the Result Match expression.pf Sense will report success on a match, failure on a mismatch.
However, there is little to no documentation provided on how to set it up properly and especially about setting up the relevant IAM access policies.
In addition to the normal public services, pf Sense also supports RFC 2136 DNS updates to DNS servers.
In currently supported versions of pf Sense, the Dyn DNS client supports using multiple Dyn DNS and RFC 2136 clients.
Dynamic DNS, will update an external provider with the current public IP address on the firewall.
This keeps a constant DNS hostname, even if the IP address changes periodically.
