DNS Issues after setting up a WAN?

[Georges I. Carraha]

Hello
 
I am including my named.conf and the reverse DNS zone files.  Could you look at them and see if I may have overlooked something?

Unless you've explicitly set up view (BIND 9.0+) it should respond
exactly the same.  I wonder, though, if you have your reverse DNS
zones properly set up on the DNS server?
