For many years I have used Zeroshell to handle local DNS for our office. Something like this:
I have a zone: office.example.com defined in the Zeroshell DNS.
I have configured ZS to use external DNS servers as Forwarders to handle requests outside the office.
Now, I would like to add management of our external DNS zone (example.com) to Zeroshell. I don’t plan to make it the actual server that responds to DNS requests, but to hold a Master Zone that gets replicated to external slave servers that would do the actual responding to the internet. These slaves would get updated when I update the Master Zone. The slaves would become the authoritative servers for example.com.
I want to make sure that my local DNS zone (office.example.com) does not get exported to the slave servers and published.
Can someone advise me if I can do this with ZS and if so a quick guide to set it up?
