  Hi,

   

  all new IM and P2P apps do not use special ports.

   

  They started to use HTTP & HTTPS protocols.

   

  To Block them, you have to know their signature.

   

  HTH,

  Tarek

  Hi Tarek
  
  My queries are
  
  1. How can we do that (trace signatures)
  2. I have EE antispyware and it is blocked via ISA 2006 EE and I want that it should update clients, therefore I need to know  
      how to identify ports used by applications.
  
  
  Thanks
