Protocol Violation

[JD Conley <jdc () MALIBUBOATS COM>]

Hello,

I was alerted today by one of our proxies (Microsoft Proxy 2.0) that it had
encounted a "Protocol Violation."  It has packet filtering enabled,
disallowing fragmented packets.  The following is an exerpt from the log
(with x.x.x.x as the 'attacker' and y.y.y.y as our proxy).  Any ideas on
what this could be?  Some sort of attack, etc.  TIA!
