[nsp] blocking Msn messenger on PIX

[Paul Stewart]

Unfortunately doesn't work unless you block port 80 as well and you probably
don't want to do that...  MSN messenger will default to TCP/80 when it can't
reach 1863.  What I ended up doing at a few sites that had their own
internal DNS was creating entries for messenger.msn.com (double check that -
it may have changed) to point to 127.0.0.1 therefore it couldn't login at
all.... Worked like a dream....

Try blocking outgoing TCP/1863 and UDP/7001
