Block P2P and IM

Hi to all

I want block some pages type (social networks,internet radio and TV)  and application with instant message like (messenger and web chats), now i have a Cisco ASA 5520 version 8.2.  I trying to make this CLI configuration< http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a0080940e04.shtml > but i can't block the application like (windows live messenger). Please if someone can help me for this or other way can i do this.  I think i can do this with my Cisco ASA 5520 or i can use other device to do this?.

Best Regards.

Block P2P and IM

Hello Adan,

I would suggest to do the following:

access-list MSN permit ip x.x.x.x(internal subnet) any

class-map MSN

match access-list MSN

policy-map type inspect im MSN

match protocol msn-in

  drop-connection

Policy-map global_policy

class MSN

inspect im MSN

Regards,

Julio
