[CentOS] Learning some sad things about the state of IPv6

We have kernel support for IPv6 in Centos, but not stateful firewall 
support.

That requires at least the 2.6.20 kernel, which means Fedora Core 6 or 
some other Linux distro.

None of the various free Linux firewalls have IPv6 support.  Supposedly 
FWBuilder can manage Netfilters for a Linux Kernel, but that seems to be 
the extent of it.

More sad facts as I uncover them.....
