DHCPv6-PD Worked With CG3000DCR Now Broken With CGA4131COM
I had 150 mbps service with a Netgear CG3000DCR and IPv6 with DHCPv6-PD worked flawlessly with my Cisco router. I decided to upgrade my service to 300 mbps and, of course, the CG3000DCR will not work with the higher speed. A technician came out to replace the CG3000DCR with a CGA4131COM for the speed upgrade. Nice that that I was able to have my phone service and Internet service on one device instead of two. The installation went smoothly and Internet and phone service is working well. Except for IPv6. After the gateway swap, IPv6 DHCPv6-PD is broken. I can do IPv6 pings and traceroutes with my Cisco router (for example Google's DNS server 2001:4860:4860::8888) with no issues. However, even with clients automatically getting IPv6 addresses, no IPv6 pings, traceroutes, or traffic will pass through or route with the CGA4131COM gateway from clients.
Since I have five static IPv4 IP's that I would have a hard time to give up, bridge mode is absolutely not an option. Having IPv6 is important.
