ipv6 dhcp server not handing out addresses

[robert at spotswood-computer.net]

Yes. Well, I used wireshark, but same thing. I see the solicits in the
packet capture, but that's it. No replies. Now that would lead me to think
firewall, but as I've mentioned, I've checked that already. ip6tables -L
-n => no rules, defaults are accept. ip6tables -L -n -t nat => no rules,
defaults are accept. Ditto for iptables, not that it should matter.

Since no one can find anything obvious, maybe the version I've got has a
bug? Anyone using 4.3.5 for ipv6 sucessfully?
