title: Zentyal: Overriding some DNS entries for some external domains to internal ip
body: <p>Id like to overwrite public URLs to point to internal IP addresses using Zentyal DNS. The goal is for all requests to an address e.g. www.example.com to be routed to an internal server e.g. <a href="http://192.168.1.255" rel="nofollow noreferrer">http://192.168.1.255</a>.</p>
  
  <p>This works when I alter the files in /etc/bind, but the changes are lost with each restart. I have tried to create a stub for these changes in "/etc/zentyal/stubs/bind" but the configurations changes are not recognized on module restart or reboot.</p>
  
  <p>How do I make the BIND/DNS changes persist across module restarts, reboots and software updates?</p>
