Reverse lookup

[Mark Gosselin]

Hi List,

Is it possible that my firewall could be configured to block reverse
lookups, but not regular lookups??
I can lookup by name and IP on my domain, and can lookup by name other
domains (ie amazon.com)
but, if I supply th IP address for amazon.com, I get a "non-existant
domain" reply......

I've scoured the entire DNS/BIND book from O'Reilly and I can't see what
I'm doing wrong..... Is there
someone out there who'd willing to look at my files and see if I am, in
fact set up correctly??? I must
warn you, however, I'm running BIND 4.9.3 (I do plan on upgrading once I
get this issue straightened out.....

Thanks,
