[nsp] Blocking KAZAA and Co. on PIX

[Serguei Bezverkhi]

Hi,



I was searching Cisco web site for suggestions on how to block KAZAA  and 
other file sharing applications on PIX. The document that I found was saying 
that it can only be implemented on a router using NBAR.



I would greatly appreciate if somebody who faced this problem, shared a 
direction they took to filter these applications.

As far as I can see I have two options it is either to bring a router with a 
firewall feature set and using NBAR to fight these applications,  or use 
very restrictive access list from inside to make sure only allowed traffic 
is passing from inside to outside.



Any idea or suggestions or different approaches are greatly appreciated.



Thank you in advance
