DHCPv6 via PPPOE not working

[Joolee]

I got a dual stack internet connection from Routit with a /64 ipv6 subnet. Connection works perfectly when setting my cisco x1000 modem to directly dial pppoa. When I configure the modem to act as a bridge, let pfsense do the ppp(oe) setup and set ipv6 on the pppoe interface to dhcp6, It won't get an ipv6 address assigned. Strangely enough, it does get the correct gateway assigned.

I can only ping the link local address of the gateway when it's set as the default ipv6 gateway. Otherwise, the pings will go through my ipv6 tunnel. (is this a bug?)

The output of ifconfig is always (with static or dhcp):

pppoe0: flags=88d1 <up,pointopoint,running,noarp,simplex,multicast>metric 0 mtu 1492
        inet6 fe80::217:a4ff:fe0d:4afe%pppoe0 prefixlen 64 scopeid 0xd
        inet *.*.*.234 --> *.*.*.133 netmask 0xffffffff
        nd6 options=3 <performnud,accept_rtadv></performnud,accept_rtadv></up,pointopoint,running,noarp,simplex,multicast> 

Setting or not setting "DHCPv6 Prefix Delegation size" changes nothing to the log or the endresult.

ppp log (stripped from ipcp lines):

We just replaced the DHCP6 client, it might work better now, please check.

Still no luck. I just updated to yesterdays build.

I hijacked http://forum.pfsense.org/index.php/topic,56880.0.html to post more information.
