It looks like no system, internal or external could access the DNS on my new server. IPTABLES was set for 53 both UDP and TCP. Firewall was OK. In fact a local system on the same subnet, thus NOT going through my firewall was denied access to the internal domain. Localhost of course works.
<SNIP> Not sure what you mean be "Localhost of course works." Are you using:
dig @localhost any mysubdom.mydom.com
to see if the DNS server is responding?
If not, try dig on your DNS both using @localhost, @int.ernal.ip.addr and @ext.ernal.ip.addr and then try it from other systems on your network.
The first thing to do is to make sure the DNS server responds correctly to queries.
