In Cisco IOS it is possible to block some kinds of p2p traffic like Skype or Bittorrent etc. All you need is just a simple rule for this:
Example:
class−map match−any p2p
match protocol skype
match protocol bittorrent
policy−map Disallow−p2p
class p2p
drop
int FastEthernet0
description Inbound
service−policy input Disallow−p2p
If it doesn’t work, try upgrading IOS and try to avoid x.0 revisions.
