IPv6 with WiFi Hub in bridge mode
I need to be on an IPv6 network to do work from home so I just got fibre installed today. Everything is working great out of the box with the white garbage can router. Using https://test-ipv6.com/ I can see my external IPv6 address, able to connect to my work's IPv6 only test server.
Next, I attempted to connect my Netgear Orbi router to the white garbage can router and turned it into bridge mode. Everything works fine in IPv4 mode. When I attempted to turn on IPv6 via the WAN DHCP mode I got nothing back except the IPv6 DNS addresses.
Any tips on getting this to work will be greatly appreciated. I do not want to be stuck on this white garbage can.

Well. A whole night of debugging and reading. I have it working. I'll leave the notes here in case anyone wants to get it working with their own router. All the details are available here: https://forum.telus.com/t5/Internet-Home-Phone/IPv6-connectivity/td-p/3521
The big gotcha is this note.
2. If the device does request both an IA-NA, and an IA-PD in the solicit message, then it must conform to RFC 7550. We are not using IA-NA so in our dhcp Advertise message there will be a NoAddrAvail message for the IA-NA, and a prefix for the IA-PD.
Most devices out there, including pfsense will issue IA-NA, follow by IA-PD request messages. As noted at the bottom of the thread. Telus is ignoring NA for "security" reasons. Which I don't want to debate about but it's questionable at best.
If you have a Netgear router, you can get to the debug page by adding /debug.htm where you can activate Telnet to get into your router. Once you are in your router, open up
vi /etc/dhcp6c.conf
You will see the sequences for requesting IPv6.
interface brwan { send ia-na 1; send ia-pd 11; request domain-name; request domain-name-servers; request ntp-servers; request sip-server-domain-name; request sip-server-address; script "/etc/net6conf/dhcp6c-script"; }; id-assoc na 1 { }; id-assoc pd 11 { };You will need to disable send ia-na 1;
That will do it.
