running 25015m sp1 kong build on wndr4500 v2

i have it setup to use native from isp with prefix delegation, if i plug my pc directly into my modem http://ipv6-test.com/ tells me i have a 6to4 connection and ipv6 is supported but through my router it tells me i do not but my local pc tells me
Tunnel adapter Local Area Connection* 11:

Connection-specific DNS Suffix . :
IPv6 Address. . . . . . . . . . . : 2001:0:9d38:6ab8:4fc:218:bc07:ad68
Link-local IPv6 Address . . . . . : fe80::4fc:218:bc07:ad68%5
Default Gateway . . . . . . . . . : ::
i have nothing else enabled under the ipv6 config besides the one setting.

what am i missing?

First off there was no need to bump posts less than 24-48 old. People are not sitting on the forum just waiting for you to post.

Your original post is very vague and is a mess as it mixes router issues with Pc issues

6to4 tunnels are the worst of the transitional ipv6 methods. Anything related to tunnel adapters on your win pc is pc related. Others may wish to help you with that but I'll pass. There is more than enough info available on the subject via google.

Now about your router issues. Does your isp support dhcpv6-pd? Is your modem compatible? Is ipv6 enabled for your account?

How did you setup dhcpv6-pd?

I did per the wiki and a few posts made by you actually, none of them worked. Yes my ISP does support it and a friend of mine got it working on stock firmware and lives about a mile from me. For some reason the router won't get an IP from my ISP no matter what config I try but I wound up getting a static tunnel working with HE and dhcp6s for all my PC's. I've been around these forums long enough to know if its not on page one it gets lost but thanks for being a bit snotty about it though appreciate it.

Does this mean your happy with using an HE tunnel or are you still trying to debug dhcov6-pd?

Do you have an ipv6 setup tab in webif on your FW or is scripting the only option?

Select dhcpv6-pd from the setup tab and leave the other default entries. Enable radvd with default settings and dhcp6s with default. Reboot and run the following commands

ps
ifconfig
ip -6 route
cat /tmp/dhcp6c.conf
cat /tmp/radvd.conf
cat /tmp/dhcp6s.conf
radvdump

radvdump will run in a loop. Let it run through a few cycles then hit ctrl-c to quit

Ok you didn't post result of ps do I can't confirm dhcpv6 client is running but from the radvdump and default routes there is no indication ipv6 is enabled for you.

Is your modem one of the models on this list? http://www.timewarnercable.com/content/dam/residential/pdfs/support/internet/twc-ipv6-modems.pdf

Is your modem a modem / router combo unit? If yes, is it in bridge mode?

Has your ISP confirmed ipv6 is enabled on your account?

When you plug your pc direct to your modem your getting the address listed in the first post 2001:0:9d38:6ab8:4fc:218:bc07:ad68 or another address? If a different address which address?

The address 2001:0:9d38:6ab8:4fc:218:bc07:ad68 is a teredo tunnel and not an ISP assigned ipv6 address.

and when you were plugged directly to the modem and ran the ipv6 it showed the 2604... address and said you had a 6to4 connection?
