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.
