Paul,

Have you custom tuned your frag3 lines to reflect the targets behind
your IDS?

Apparently not.

preprocessor frag3_global: max_frags 65536
preprocessor frag3_engine: policy first detect_anomalies \
                          ttl_limit 10

But the targets behind an edu IDS would be "all of the above".  :-)
