No NAT needed since they share the network stack under Jails v1 they

You're clearly exploiting a bug in FreeBSD 6's jails. It must get confused
and send your public IP on those packets. I have no idea how it processes
the return traffic successfully, but "that's a neat trick!". There is no
possible way for this to work without NAT or whatever bug this is. If a
Jail has a 192.168 IP all packets would leave with a source of 192.168.
When Google or whoever on the internet gets your packets it would see
192.168 and probably drop it because that's not a publicly routable
network.
Without NAT it's impossible for any device anywhere on the planet to
access the internet with an RFC 1918 IP address.
I urge you to share your experience on the freebsd-jail@ mailing list.
Those guys might be able to lend some further insight. I bet the change
came with the update to jails that allows multiple IPs.
