So as I was going through my Defense Center yesterday I saw that I was getting hits against IPv6 rules.  It looks like that these are all mac clients that someone decided to turn on IPv6 for some reason.  More than likely these are Leopard clients since IPv6 is set to be automatically configured.  I have noticed that on my home network my mac clients and mac wireless APs were all set to automatically use IPv6.  I really believe that this is a bad idea on Apple’s part to have IPv6 automatically turned on.  Most people have no idea what it is or why they have it.  To have this turned on and then suddenly there be some vulnerability that people have no idea about is going to be a bad day for a lot of desktop techs and home users.
