Description (partial)

Intrusion events will show an "Original Client IP" that does not match with the packet data of the event.

The events are generated from traffic where any given TCP stream contains multiple HTTP transactions.  This generally indicates that the sensor is 'upstream' from a web proxy of some nature.
