Hello !

I encounter the problem, that DNS resolution doesn't work out properly.

When a clients asks the internal DNS to resolve a host's name it takes
seriously long resulting in a time-out. The internal DNS forwards the
request
to a specific external DNS server but obviously gets no answer. Instead
its
digging recursively a series of unknown DNS server.
After about half a minute everything's fine and the host will resolve
within
 a few ms.

When digging the external DNS directly everything's within normal
response
times.

I did a test setup at home using the same configuration files and
 everything's working out just fine.

The firewall is a hardware device from Nokia running Check Point
Firewall-1.

Does anyone know that problem? Which ACLs work out fine and are secure,
 still? Any other ideas?
