I need help?????? dns and nslookup

[Marc.Thach at radianz.com]

David,
I think you'll find that the resolv.conf is OK, but the message comes from
nslookup wanting (and not getting) a reverse resolution for the server
name.  As they all say, use dig instead of nslookup.  As for the firewall
log warning, that looks like a DNS response being blocked (maybe the
aforementioned revese lookup).  You will have to change your firewall rules
if you want to perform these DNS lookups.
