You said that when you do a normal dig or host lookup from the shell
there is no problem, so one would assume that using dnscache the queries
would be rfc compliant and not trigger the IDS.

Because of the way the PIX handles NAT/PAT you normally need to turn on

have PDM access you can enable them with a couple of mouse clicks. A lot
is dependant on how the network is configured.
