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.
