I'd like to use Mac OS X 10.6.7 Snow Leopard Server as an Internet gateway. My router would connect to the Internet facing NIC on my Mac Mini server and the internal NIC would connect to a WiFi access point.
I want to be able to track the bandwidth users on the WiFi network are using, but I am aware of the fact that MAC addresses on wireless clients are easily changed.
How can I do bandwidth accounting based on WiFi clients without MAC addresses, logons each time and having the Internet gateway server act as a DHCP server ?
UPDATE - It appears I want to run RADIUS for WiFi auth and usage accounting...is this available in server/daemon form for Mac OS X 10.6.x Snow Leopard Server ?
