Here is the diagram.

Public IP for DNS1 is 66.15.233.17  DNS2 is .18
    66.15.233.16
ISP-->Firewall-+------+
               |      |
     [192.168.0.1] [192.168.1.1]
              LAN    DMZ
               |      |          
            SWITCH  SWITCH --+-DNS1 [192.168.1.17](Master)
                             |
                             +-DNS2 [192.168.1.18] (Slave)

>From both DNS servers locally I can dig external sites.
>From DNS1 I can dig my own domain.
>From DNS2 I get a server failure when I try to dig my own domain.  I have created a slave zone on DNS2 for my domain.
>From both DNS servers I can do an NSLOOKUP from a remote-site Windows XP machine of external domains.
>From DNS1 I can do an NSLOOKUP from a remote-site Windows XP machine of my domain.
