That's presumably the answer but I don't know why unless IPv6 support is
compiled into ufw. I don't have ufw running at all on either my desktop or
laptop (11.04) and it's set to no in /etc/default/ufw and IPv6 works fine.

FWIW I have radacct running on a Dreamplug running Ubuntu 9.04 with a Sixxs
tunnel and it just works. No help I know but I'm quite proud of it :)
