Any updates on dual stack router, SMC D3G CCR?
Lots of discussions about getting the Comcast gateways working with routers but they are some months or years old. Might be worth asking this for current status.
I have an SMC D3G CCR, 1 static IP, in gateway mode (i.e. no DHCP). IPv4 has been working flawlessly for years. Now looking at how/if IPv6 can be supported. Have a Linux router/firewall/NAT box behind the gateway. I have the router working nicely under IPv6: I can ping6 everywhere, and even get a 10/10 score at test-ipv6.comcast.net. It is using the Wide-DHCPv6-Client package to get the config info from the gateway and have tried having it request both /56 and /60 prefixes using the IA_PD request (although copied from apparently reliable sources, the config has not been explicitly tested for that), but I get no delegations.
I have tried lots of the tricks to try to trigger getting one, but no luck (power cycling gateway, changing router's WAN ethernet address). I also see numerous reports that the D3G is just not going to work. I did call tech support last weekend, got a ticket sent to Tier 2, but nothing back (and even though my knowledge on this topic is rudimentary, it was a lot more than the tech's -- sad).
Is this a hopeless cause? Will the D3G CCR just not work? Or do I need to persist and find the right person who knows how to provision the gateway to hand out a /56 or /60 prefix?
