I think this is only fatal with nslookup, but DNS servers should be
able to reverse-resolve their own IP address to a name and apparently
your forwarding server doesn't know your private addresses either.
What does 'dig @localhost' say on the box itself?

The right fix is to configure either this or the upstream server
as primary for the 192.168.0 zone.  Otherwise you'll toss thousands
of these queries up to the root servers.

zone "0.168.192.in-addr.arpa" IN {
       type master;
       file "192.168.0.arpa";
       allow-update { none; };
};
If you don't know the format for the zone file mentioned, you
might want to use webmin to build it.

Does your upstream server resolve that domain or your private
addresses?
