DHCPv6 client no longer gets a response from my new Cisco Business Gateway -- Netgear worked

The subject says it all.   I have a business account with both static V4s and a /56 static V6 prefix.   As we all know by now, I had to request, via DHCPv6, a /60 from the modem.  The Netgear answered the request just fine to my routers (pfSense, Mikrotik).  I've just upgraded to the new Cisco business gateay as I've gone to the 250/25 service.  V4 static works, but V6 simply does not respond to any V6 DHCP request.  Devices connected directly to the LAN ports get addresses, but not routers.    The routers do get an RA supplied /64, but that's it.


What am I doing wrong or is this broken again?

Hi jantypas.


I can certainly review your gateway and your prefix information. Please private message me your full name, the name of the business, the full service address and the phone number associated with your account.
