Nessus and PacketShapers do not mix. The average survival time of a
PacketShaper in the path of a Nessus test was about 5 minutes.

In fact just running nmap was quit sufficient to render it helpless.

Do you mean _through_ it or _to_ it. If "through it" I  would be
surprised as I have done Nessus scans through a PacketShaper in the
past and did not have any issues.

That is a definit THROUGH it. Is simply chokes on the amount of sessions
it needs to handle. Mind you that this was with nmap testing 30 host at
the same time with an aggresive policy.

It might have been fixed by now. But 2 years ago it was a perfect way to
perform a DoS attack on a network behind a packetshaper.
