Resolving internal and external DNS records

[certolnut]

Hi all

I only do networking rarely, unfortunately this has fallen into my lap..

Our firewall will not allow our internal computers to resolve our external
addresses for security purposes.

For example.. if the internal name and ip address of our web server is
"AAAwebserver" and "10.1.1.7"
the external name would be www.AAA.com .net or .org.
and 67.100.345.77

So if my internal users type in www.aaa.com, the browser will attempt to go
to 67.100.345.77, but the firewall will block it (it won't allow this set of
internal to external to internal query). So I am forced to tell my users to
go to http://AAAwebserver/ instead, which is very confusing to them.

Is there some sort of DNS record that I can add to my internal network that
will allow me to resolve www.aaa.com to 10.1.1.7?

Thanks, I'm sure this is clear as mud...

Sure. Add the whole thing. And/or, ad it to the local computer's hosts
file.

No, not exactly. What you need to do is change the INTERNAL
(view) of your external zone to provide ONLY the internal
(reachable) addresses to internal users.

If you don't actually have a Shadow DNS (split DNS) setup then
you need to add a NEW version of your zone externally. This
means you will have two Primaries (masters), one external and
one internal. This also means you must manually add records
twice, once for the external version and again for the internal
version (of the zone.)

Simply put, as the others stated but just to simplify what you need to do,
create an aaa.com zone on your internal DNS, and create a www record under
it, and provide the 10.1.1.7 for the IP address.
