comcast xfinity (residential) non-responsive



I have been beating my head against comcast for a while now.  I would really like to go native ipv6.

1) my cablemodem is in bridged mode
2) my wan port is set to dhcpv6 (and dhcp for ipv4)
2.5) I am requesting via ipv4 connectivity
2.6) i am requesting prefix size 60
2.7) I am sending a prefix hint
3) ipv4 works fine.

I see the link-local addresses for both wan and upstream, but no global ipv6 at all.

I haven't configured my lan as I am using hurricane electric at the moment. 

When I filter the dhcp logs for dhcp6c, all I see is:

Jan 2 20:47:39   dhcp6c   85061   extracted an existing DUID from /var/db/dhcp6c_duid: 00:01:00:01:21:df:12:d0:00:0d:b9:21:55:e4
Jan 2 20:47:39   dhcp6c   85061   failed to open /usr/local/etc/dhcp6cctlkey: No such file or directory
Jan 2 20:47:39   dhcp6c   85061   <3>["/var/etc/"] (31)
Jan 2 20:47:39   dhcp6c   85061   /var/etc/dhcp6c_wan.conf:3 IA_PD (0) is not defined

What do I do?
