Hi,
The way I understood your problem is that you need two DNS servers behind NAT and you must setup two DNS servers. As others indicated, the 1st step of the solution is port-forwarding, the way you setup your webserver in your router. Second is you need two public IP addresses, one for your web server and at the same time a primary (can be secondary) DNS server, the other public IP is for the second/secondary DNS server. At least you need two machines behind NAT to power your Web and DNS servers. If your main machine is powerful enough, you can easily setup a virtual machine as a secondary or primary DNS server.

PHNET is the registry for the EDU.PH domain name. The provide domain registration, DNS hosting and web hosting services. However, we would like to run our own DNS for this purpose. Indeed for the setup that's behind the NAT port-forwarding is the solution. PHNET requires that you must register at least 2 nameservers for validation. I will try to contact PHNET on this issue. Thanks again guys for your helpful suggestions. Mabuhay UBUNTU-PH community!
