I use VIMAGE/VNET jails with IPv4 & IPv6 addresses for public access. 
VIMAGE/VNET has been stable but only supports ipfw firewall which 
includes a bug where all the VNET jails IPFW firewalls log files write 
to the hosts IPFW firewall log intermingling the log records. I use 
qjail to create and manage my VIMAGE/VNET jails.
