[FW-1] Effective way to block MSN Messenger/Google Talk on R65/R70?

["M. N." <[EMAIL PROTECTED]>]

Hi,
Has anyone found an effective way to properly block all form of MSN
Messenger/Google Talk?

 

So far, I've tried the following without  success:

-Smart Defense in R65 and IPS in R70 (all MSN/Windows Live related
protections activated)

-SK35174 by adding a custom HTTP header filtering
\gateway.messenger.hotmail.com

 

Or is this a losing battle without more advanced DPI products?

 

Thanks
