The OP who posted is the one who marked it solved, for the OP . For others known issue from Rolande 9/02 Apparently there is a memory leak situation with IPv6 on the 2Wire/Pace gateways that is being actively worked on for resolution. Hence, why the widespread IPv6 rollout to existing RGs has been kind of stalled. The new firmware is also breaking customers with existing IPv6 tunnels passing thru from a router behind the RG which is also in the dev pipeline for fixing. These issues do not appear to exist on the new Motorola NVG589 platform but, regardless, the IPv6 profile is not being enabled by default, yet
From ATTDimity posted 10/4 working to enable IPv6 for all of our consumer broadband customers and when we have a firmware update for IPv6, we will push it to our devices and enable it. For more information, please refer to www.att.com/ipv6.
