MacOSX IPv6 Networking Knowhow

First, the bad news. There is no clean, elegant way to firewall IPv6 traffic in MacOSX. The Firewall GUI control panel won’t do it. But the internal firewall that runs behind the GUI is FreeBSD’s ipfw packet filter, which does support stateful filtering. I’ll try it soon on a Mac, but I’ve used this on FreeBSD and it’s not too awful.
