Greetings,

I've recently conducted testing using a piece of software called "Connectify".  This software allows a user to turn 
their wireless laptop into a Wi-fi Hotspot.  The software creates virtual wireless interfaces for its hosts and then 
utilizes NAT to make the connection appear as if it's coming from the Hotspot instead of the connected hosts.    By 
doing so a student is able to allow other students to piggy-back off their wireless connection, with only the one 
device/user authenticated on our student, wireless network.  When viewing the logs of our firewall, connections appear, 
in regards to both I.P. address and MAC address, as if the connections are originating from the Wifi-hotspot and not 
the connected hosts.  I suspect that Internet tethering such as this may become more prevalent as more smartphones 
begin to  incorporate this functionally into their operating systems.

Has anyone else received any other reports similar to this and has anyone come up with a solution to help remedy the 
situation?  Any and all feedback would be welcome.

Thank You,
