Out of curiosity, why was that causing problems ?

Joel?  This has been an issue as long a I've known snort with stream5 +
checksumming.  What is the root cause?


Ultimately the NIC or Virtual NIC if I am understanding the question.  Check out https://www.snort.org/documents

On the page is a document written by William Parker, its called “Possible Packet Loss During Reassembly for Snort 
IDS/IPS Sensors”  It’s under “Additional Resources”.
