Thanks for the links to the details.

>From my reading of the details at the google link my firewall
is secure as long as the skype client software is not installed
on any of the LAN pcs behind my firewall.

I added deny rules for the ip address where the skype client can
be downloaded from so employees can not install it.

Does anyone know if there are any other client software products
that use this same technique.
I will add their download ip address to my firewall rules also.

Thanks
