Greetings,

I've put ip nbar protocol-discovery on the FastEthernet interfaces of my Cisco 2800 (ver 12.4(4)). I created a class-map to match the protocols of some known p2p apps, created a policy-map to drop the matched traffic and added the service policy to the interface. The problem is, when I run "show ip nbar protocol-discovery" eDonkey is not being blocked. Below is the relavent config:

class-map match-any p2p
 match protocol edonkey
 match protocol fasttrack
 match protocol gnutella
 match protocol kazaa2
 match protocol winmx
 match protocol novadigm

 policy-map block-p2p
 class p2p
   drop

interface FastEthernet0/0
 no ip address
 ip access-group 150 in
 no ip redirects
 no ip unreachables
 ip nbar protocol-discovery

What am I missing?

Looks like you may need the new edonkey pdlm. Cisco has the instructions here.  Other than that your config looks good.  

I think the older versions of limewire were covered by how you are doing it but the newer versions need the new pdlm.

Hope this helps.

Sorry for the delay, I've been on vacation. I'll download the new pdlms and give it a shot.
