Have you looked at D-Link's DIR-825? It has most of the things you're looking for. The DIR-655 is a more affordable option.
Haven't had the chance to look at that one. Will check it out.
In regards to (2), is it even possible to do DHCPv6-PD on with a SLAAC WAN?
It had better be, as IOS 12.2 SRE only supports SLAAC + DHCPv6-PD. Most of the Cisco documentation I've seen, says that is their beautiful layout. No more proxyarp/nd. Instead, assign a /64 to each subinterface, perform SLAAC, then hand out prefixes via DHCPv6-PD if someone needs a prefix.
The DIR-825(Rev B) running firmware 2.05NA does. From the status screen:
IPv6 Connection Type : Autoconfiguration (SLAAC/DHCPv6) Network Status : Connected
WAN IPv6 Address : 2610:b8:0:234:218:e7ff:fef8:66dc/64 IPv6 Default Gateway : fe80::c67d:4fff:fed6:5401 LAN IPv6 Address : 2610:b8:100f:1:218:e7ff:fef8:66db/64 LAN IPv6 Link-Local Address : fe80::218:e7ff:fef8:66db/64 Primary IPv6 DNS Server : 2610:b8:0:3:215:c5ff:fef3:f9c8 Secondary IPv6 DNS Server : 2610:b8:0:3:215:c5ff:feee:9448 DHCP-PD : Enabled IPv6 network assigned by DHCP-PD : 2610:b8:100f::/48
The latest firmware has fairly good support, but is lacking configurable v6 firewall settings. I haven't done any firewall testing yet, but I'd imagine all incoming v6 connections are blocked.
The Emulator hasn't been updated yet to reflect the options in the new firmware, but this should give you an idea of what the configuration looks like:

The DIR-615 should have similar support, but I haven't upgraded it yet.
Hello, As for the DIR-615, it should, but it doesn't...At least, the E3/E4 revisions I had. I contacted D-LINK support and was able to get a beta build that seems promising. But DHCP-PD over PPPoE works relatively well, minus a couple of little "features". I am hoping to have that hammered out soon, as the 615 is a capable little sub-50$ home CPE. But D-Link engineering seems receptive to my observations. I have to check the state of the firewalling in it too ;) Chris

My concern as an ISP is the fact that we provide our own CPE, but customers often buy off shelf CPE. This will lead to serious interoperability issues if the whole market doesn't get their act together. Jack

There's a fine line we're trying to hold with what we support. We want to establish a recommended list of residential grade routers for our customers (where appropriate), that they can purchase themselves off the shelf, without having to deal with the inevitable "you sold me this router, so you need to make it work with my Wii and I don't feel that I should have to pay you" type of headaches, if we were to actually sell the routers ourselves. That rules out 3rd party firmware like dd-wrt, since the customer is unlikely to get support when calling the vendor. At this point, I'd be happy with two good options (two different vendors) to recommend. So far, D-link is looking good. -- Dan White

Yeah, don't get me wrong. In most of our network, our CPE is bridging only. Customers wanted wireless and a few of the telco's were adamant about including it in their CPE (so the customer didn't have to go buy a wireless router from walmart). 90% or more of those wireless CPEs are still fully bridged (even the wireless is bridged to the wan). I've tried my hardest to keep things where IPv6 from our side will just work. What a customer buys is their concern, but we still have the danger of gear which just won't be interoperable with our setup. Jack
We've sold routers for years, but make it clear to our customer that we are doing this as a convenience to the customer and that we are not responsible for it. It's worked for hardware failure, and since we end up providing initial support for home wireless routers, having a model we're familiar with makes it easier.

I agree with you, but I also know my telco's. It would go horribly wrong. :) Jack
