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? - -- straightLiners IT Consulting & Services IT Security Department Sebastian Schneider Metzer Str. 12 13595 Berlin Germany Phone: +49-30-3510-6168 Fax: +49-30-3510-6169 Diese E-Mail enth�lt vertrauliche und/oder rechtlich gesch�tzte Informationen.
