Security Incidents: Re: HTTP 408 errors

[James Golovich <james () wwnet net>]

I would suspect that these are all nimda/code red but are getting blocked
at your border by NBAR on your cisco.  The router drops the packets that
have the nimda signature, but there isn't any way for the router to know
to drop the syn-ack
