Thanks Barry for the heads up on the email etiquette its been a while 
since I have last posted to mail lists. I will provide the proper 
information next time. Anyway, I actually solved the problem earlier. 
It turned out to be a Reverse DNS Delegation problem with my ISP. They 
will be forwarding my IP Block onto my name servers and that should 
take care of the reverse lookup problem Im getting on my external IPs.

 Thanks much,

  You haven't provided any details of the types of errors you're 
  so I don't know how you expect anyone to help you. And what do you 
 by "both of my reverse lookups"? That wording suggests that there are
 two specific reverse lookups that you always do, and they're both
 failing, but that doesn't help us understand the problem.

 No one wants you to send them your config files directly, unless you
 hire them as a consultant. Post some example "dig" commands (please,
 not "nslookup") and your config files to the group.
