Using ipv6 with a broadband ISP

[greenturtle99]

I have been attempting to autoconfigure IPV6 as a client on the MSR 30-40 router with a common carrier ISP (Time Warner) without success.  If I connect a client computer directly to the broadband modem, ipv6 autoconfiguration works perfectly with the global unicast address configured as well as DNS.  IPV4 is working perfectly.

ipv6 is enable globally

My interface configuration is shown below.

interface GigabitEthernet0/0
port link-mode route
description WAN-INTERFACE
firewall packet-filter name wan_inbound inbound
firewall aspf 1 outbound
nat outbound
ipv6 address auto
ip address dhcp-alloc

After ensuring a clean reboot of the router and the broadband modem I am unable to access ipv6.  I have also tried static autoconfiguration.

The interface shows some basic autoconfiguration but no global unicast address.

GigabitEthernet0/0 current state :UP
Line protocol current state :UP
IPv6 is enabled, link-local address is FE80::D27E:28FF:FEC6:1693
No global unicast address configured
Joined group address(es):
FF02::1:FFC6:1693
FF02::2
FF02::1
MTU is 1500 bytes
ND DAD is enabled, number of DAD attempts: 1
ND reachable time is 30000 milliseconds
ND retransmit interval is 1000 milliseconds
Hosts use stateless autoconfig for addresses

I am receiving packet events (show via the debugging command).

*Jan 6 16:34:14:543 2014 HP IPV6PP/7/debug_ipv6:
Receiving, interface = GigabitEthernet0/1, version = 6, traffic class = 0,
flow label = 0, payload length = 154, protocol = 17, hop limit = 1,
src=FE80::F145:EA78:5225:8D3F, Dst = FF02::C,
prompt: Input an IPv6 packet

src=FE80::F145:EA78:5225:8D3F, Dst = FF02::C,
prompt: Ingress interface did not join the group address!

Also, I am receiving RA events.

*Jan 6 17:20:20:902 2014 HP DHCPC6/7/DebugEvent:
RA Event: RA packet received on GigabitEthernet0/0. M-Flag: TRUE, O-Flag: TRUE.

So some amount of communication is happening.  Information about the ISP on the Web is unfortunate but indicates that clients using stateless autoconfiguration should work.  This is confirmed by my tests with computer clients except the MSR 30.

Does anyone have a suggestion about configuration or ideas for collecting clues?
