On the server, what is in /etc/resolv.conf? What happens if you ssh
into the server and try to do, eg
dig <sending client ip>@<nameserver ip in server /etc/resolv.conf>
for example
dig 192.168.0.10 at 123.123.123.123
and how fast does it come back with a reply?
Are you using a realtime blackhole for lookup? Maybe that is slow.
