[c-nsp] ASA filtering of P2P apps

[Paul Stewart]

Hey Chuck...

We tested this in one of the initial 7.x releases.... specifically we were
interested in blocking MSN messenger an an application (not
source/destination IP and/or port numbers - that's a huge pain in the
butt).... anyways, never got it working but according to Cisco guys it is
supposed to now... 

The initial releases referenced "messenger" but Cisco was referring to Yahoo
Messenger versus MS....

Just two cents worth...;)

Anyone using an ASA to filter/limit the various popular P2P applications?
It seems that the functionality exists via the regular expression capability
in 7.x.  I'm not finding any concise examples of the exact regex that will
match the various protocols.  Anyone want to share what they're using?

Thanks,

Chuck
