UVerse IPv6 with Tomato router in passthrough mode

 Got it working. Use DHCPv6 with Prefix Delegation.

What Settings did you use on the Tomato router under the DHCPv6 with Prefix Delegation?

Prefix Length?

Request PD only? Checked or unchecked?

Any Static DNS servers?

Accept RA check boxes?

My router gets an IPv6 address, but my devices on the LAN are not.

IPv6 at least in my area is not working because AT&T screwed things up on their end. You get assigned an IPv6 but no web access through it. About two months ago, when I got the 1Gbps service installed it used to work. So now I just decided to disable it on my personal router.

Make sure have latest version. This is Toastman Tomato 1.28.0511.

DHCPv6 with Prefix delegation on Tomato as shown above no longer completely works with ATT UVerse. Devices are assigned IPv6 addresses but cannot access IPv6 websites.

Does anyone have any update on this issue or a workaround they've found?  I can access IPv6 websites like domains.google.com just fine when directly connected to the NVG589 but I can't access them when connected to the tomato router; even with IPv6 enabled on both devices.

I specified Google's IPv6 DNS servers, restarted the router and now things appear to be working correctly.

Also, make sure to restart your computer as well.
