You are correct, of course.
It shows that l I haven't got my head around the
whole ipv6 issue, right?

I wonder: does this tunnel thing work even if you have a dynamic ip on
the public side of your broadband modem / router?
I my case, my FreeBSD gateway and firewall sits behind the broadband
router, and have private ip's on both interaces (internal and external).
Do I need a public ip on my gateway in order to use a tunnel?
