Hi Fluvio,
First i have to congratulate you for the great job you are doing with ZS. I’m using it as my main (master) and secondary (slave) DNS server in a couple off servers with ESXi.
One of the features i really hope you implement is a way to update DNS records from remote clients with dynamic IPs. You can call it my personal DynDNS service. 😉
I created s script to do this in Windows, but since i upgraded to ZS is one of the features i miss.
Keep up the good work.
