Questions about DNS that I didn’t see answered in best practices…

Maybe I missed this and if so I apologize- I’m feeling pretty muddled trying to plow through this.

When setting up an OSX 10.4 server that I would like to have OD working on I know I need to set up reverse DNS. Does this need to match the forward DNS, or is simply getting an answer back on a reverse DNS query sufficient?

Also, when putting the server beind a 1-to-1 NAT- do I need reverse DNS to be functioning for the server behind the firewall, i.e. doing host 192.168.100.10 should return server.domain.com, the same as if I do the host on 11.11.11.50 (the external IP)? if so, where do I put in that entry- just run it on the server? This also plays into having a second server as an OD slave- does that also need reverse DNS out to the internet, or only on the local LAN.

My thought is that if the DNS is running on one of the servers and specifies forward and reverse DNS on the LAN then that would be sufficient. The external IP address is just gravy (and useful for web/mail/calendars/ etc- but not necessary for OD). Am I far off base?
