DNS configuration fro bind-9.0.0

[Ling Ling]

Dear all,

I am configuring BIND-9.0.0 on a FreeBSD 4.0-STABLE box. I need to configure it to be our office internal server (with 192.168.0.x ips), externally, using one class C IP to go out. Because this is a testing server, so the actual DNS does not host in here, but with our ISP. Eventually, this server will be replacing the primary DNS.

Any ideas on how to do that ??? 

Regards,
Chan
