 Subject:  DNS behavior
 Date:  Tue, 25 Nov 2008 12:38:20 -0200

I'm getting a strange behavior with DNS using Monowall 1.235.

All our clients are using monowall as their gateway and DNS.

Monowall is configured as a DNS forwarder to our 3 real DNS servers
(which are outside the monowall controlled network).

When I'm on one of our windows client boxes command line and type
"nslookup <some random server>", I get a timeout in the response. But,
if a try to ping that name, open a web page, etc, it does resolve
without problems. The Monowall server has a relatively high load, but
it's not overloaded (the cpu usage stays usually between 20% and 50%,
with a load of

Does that make any sense to anyone? Did I miss something painfully

Any help would be appreciated.



Output sample from the nslookup:

DNS request timed out.
    timeout was 2 seconds. Time
d out

Servidor:  UnKnown
