DNS and NAT

Thanks for all your answers, guys. But the thing is that I am currently 
using a permanent mapping and the MS DNS domains are defined in the private 
ip address although the firewall maps it to a public address externally. I 
can't query the dns server from the outside world.Do I need to do something 
else to make it work ? However zone transfer to the dnssec1.singnet.com.sg 
and dnssec2 seems to work. I was thinking of removing the delegation to my 
dns server hq.sbs.com.sg making it a sort of 'stealth' master config. will 
this work ?

Another question. Right now I am thinking of converting the MS DNS to BIND. 
I understand that 8.2.2 supports the NT platform. Is there support for WINS 
as well ? If not, is there any way to integrate the WINS with the BIND DNS 
service ? This will be for my internal DNS setup.

Thanks again.
