If you're absolutely sure they have proper IPv6 instead of 6to4 tunneling in your area... here's my working dhcp6c.conf

Make sure to enable the proper packages so they're run at startup and be sure they're running.

Here's my ifconfig output:

And... my RADVD configuration:

And lastly, my /etc/config/network

I wasn't aware there was some script to update the prefix, I'll look into modifying the script posted above earlier so I don't have anything configured static.

Edit: Fixed things, masked a few things... like 3 times.

Thanks for posting your configuration. I only have subtle differences in configuration - /var/etc/radvd.conf does not have the prefix section and /var/etc/dhcp6c.conf has an additional section within id-assoc pd 0.


I'm thinking my area is 6to4 and not native IPv6 as I originally thought. I'll have to hookup my laptop again when I get home to verify.

It appears my area is not native IPv6 (or at least not anymore).

When I first hooked up Comcast about 4 months ago, I remember scoring a 10/10 on test-ipv6 and verifying I had native IPv6. I've switched modems since then, but that is all that has changed. Thanks everyone for your help, at least I know I'm ready when native IPv6 arrives.

What is the brand and model of your new modem?

Zoom 5341J. My modem died about 30 days after installation. Zoom sent me a replacement. So I swapped for the same model & brand, just a different physical modem.

You should give NetDog a PM to have him check your CMTS for v6. Just provide him with your modem's MAC and your IPv4 address.

PM sent. I'll let you know what he finds.
