Opps, I thought I said,
"... that is being stopped from leaving our site .."
It is originating in our network, our "egress" router is dropping the packet
and logging the event because it has an incorrect source address. My sensor
is not in the right place to capture the data. (Although, I can remedy that).
My senerio was that some virus or shrink wrap software from some
unreputable vendor was sending signals out with a forged ip source address.
The content of this packet could have credit card info, user habit data,
disk directory information, local file content, etc.
Probably enough said about this subject. ^%)
