Thanks for your help. I have a windows 2012 r2 server we are using for an internal DNS. This DNS server requires and external connection in order to use GADS (Google apps directory sync) and Google password sync. Is there a better way to make these services work without adding a forwarder to a public dns or my current solution which I would ideally like to look like this:
User -> Internal DNS -X- Public Dns (For internal Resolutions)
Internal DNS -> Public DNS -> Google services
User -> Public DNS (For external resolutions)
So my issue is stopping my internal DNS then forwarding user traffic externally, but keeping the DNS's external connectivity.
Thanks again :)
