Understand of course, which I'm sure you do, that the flexresp
preprocessor is going to be time-dependent. I've seen it used
effectively in environments able to successfully reset connections but
if you want true IP accuracy you'll want to go inline.

Also, if you are in a high bandwidth environment, take a look at the
libpcap alternatives like Phil Woods and pf_ring3 (offloads packet
processing in a ring buffer in memory)

You may also wish to check out ClamAV. Though, their are discussions
right now of how much bandwidth it can actually handle as reports have
been pretty poor.

The question is which one of the choices is the most effective?  I have tried flexible response and it is not effective and I do understand the technical issues.
