I kind of thought it would be self defeating to have the
records automatically update because you have to change
the IP's from public to private.

I'm having a setup problem with this Internal DNS server,
I created the new zone on the internal DNS server the same
as my zone on my external DNS and it now points to my
internal DNS servers private IP instead of my public IP.
Now when I go to pull the site except from the external
DNS server all I get is a DNS error where the site can't
be found so I'm pretty sure I set this up wrong?

When I nslookup the domain name on my internal DNS server
it resolves to the private IP of the DNS server, shouldn't
it resolve to the public IP or at least the IP of the
external DNS server?

My AD name is the same as my external zone that I added so
I assume the FQDN of my internal DNS is
Local.domainname.com.

???????
