[c-nsp] how to forbid MSN traffic on PIX

[Giles Coochey]

I believe that version 7.2 has IM traffic inspectors, which include
Yahoo! And MSN.

As you may know msn messenger traffic will work on either tcp/1863 or
tcp/80.Since tcp/1863 is blocked most of the times,most of this traffic
will work on http.
I am aware Cisco PIX 7.0 does have http inspection capabilities but you
should check if there is any that will search on http headers (such as
in Cisco IDS) contents which is the only way I've achieved blocking it
with Cisco tools.
