DHCPv6-PD still broken on CGA4131COM

I attempted this post before but apparently it only saved a draft with my message tags set - let's try again. I'm running into the exact same issues as in other threads with a static IPv4 address and attempting DHCPv6-PD; it appears only holmosapien has gotten a real fix, and I'm hoping to piggyback

I've been asking for this to get fixed for over two years with the GCA4131COM. I've had multiple techs out, had a phone conference and screen share session with folks in Philadelphia, had two escalation managers and yet nothing is solved. My tickets

Can not get internal IPv6 traffic to route with the CGA4131COM

Will Business Class actually support routing static IPv6 blocks?

I run a firewall between my network and the Comcast "cable modem", but I'm unable to get DHCPv6-PD to work, and I'm guessing Comcast has turned off DHCPv6 entirely from what I'm reading. If that's the case, how am I supposed to route my /64 (or "/56", but we really only get a /64, and I'd be happy w

@Comcast_phil You didn't answer his question. It was: "how am I supposed to route my /64". The comcast IPv6 support has been beyond frustrating. I can't get my internal IPv6 to route either.

Issues with bridging / static IPv4 & IPv6, CGA4131COM

Hello! I recently moved my business service and the technician installed a Technicolor CGA4131COM.
