[cisco-voip] how to block peer to peer and chat

[ash AD]

Because NBAR can inspect deep packet information thru to the application layer data, it is not subceptable to port changes. Here are some of the L7 p2p applications NBAR can recognize:
   
  BitTorrent 
  DirectConnect 
  eDonkey 
  eMule 
  FastTrack 
  Grokster 
  JTella 
  Kazaa (as well as Kazaa Lite and Kazaa Lite Resurrection) 
  Morpheus 
  Win MX 
  Gnutella
   
  As far as stopping Java based IM and Chat engines, CSA might work for you.

 you need something that can look into the packet for that
..  ports change if blocked.
   
  Look at netinforcer or packetshapers, etc.
