Hello,

Is there a way we can block Skype in PIX. I know that we can block skype in Checkpoint ,but dont know how to block skype in PIX. I checked the way skype works and each time the IP it connects seems to be different and it uses port 443 and 80. So is there we can block this.Is there any thing unqiue by which we can block or do packet inspection and block in PIX.

In pixOS version prior 7.0 its not possible. In pix OS version 7.0 you can use aplication inspection on port 80

Can you elaborate on how to do this using application inspection or point to a reference document.

Skype is quickly becoming we may need to control on our network.

Dear all

As skype use the port 443 and 80 and you cannot block this port the best way is to install a third party software for URL filtering like websense or other, for websense you can block many peer-to-peer software like emule ...ect
