Building DNS nameservers

Hi i think this is a simple question but i want to make sure that i dot all of my I's and cross my T's

i just built out two DNS servers destined to be NS1.XXXxxxx,com and   i logged on  to and added the name servers with their public ip's.  i have nat'd my public ip's to the servers internal on the network and opened port 53 TCP/UDP

is there anything else that i need to do on my DNS servers?  should i enable secondary BIND?

"secondary BIND" is just one of ways to keep DNS zones in sync.
i.e you edit master zone and other server gets updated with changes.
For a bare minimum you did what needs to be done. Nothing else is required assuming you configured DNS correctly.

Probably not. This setting should only be enabled if you'll be transferring zones hosted on these DNS servers to other servers running BIND (a non-Windows implementation of DNS). It controls the format of the zone transfer. More info can be found here.

This may be a stupid question, but have you created the appropriate zones on these servers? I'm only asking because you didn't specifically mention it.
before setting the nameservers live you should test them using something like nslookup from an external network. this way you can fix issues before any public connections are attempted.
