Subject: MSN appears to be being a bit snoopy via a Hotmail server...

We are running a Linux floppyfw on the outside, splitting into an
unrestricted work space, and a stronger firewall to protect the office
side of things.

A computer was being setup that is running MSN software, and during it's
1 day on the benches, our good firewall recorded the following hits from
the below noted site, all of which were aimed  * directly *  at the IP
address of the internal firewall's NIC (represented by "xxx.xxx.xxx.xxx"
below) climbing over the floppyfw to do so...

And from our internal firewall's proxy logs, noone here was logged into
Hotmail or MSN servers during these times...

The above mentioned computer's time in our shop is the only thing I can
relate this traffic to, as noone is allowed to run MSN software on any
of our Linux workstations...
