IPv6 Native with Telstra, Australia

They do not have to know anything about pfSense. They should be able to tell you what is required of ANY dhcp6 client to pull an address and PD. Then we just make pfSense do what they require instead of guessing.

What I've given you is everything they have given me when I've asked. I don't think they intend on giving me any more info unless there is a specific question you want me to go back and ask them. They haven't provided me with any further info. I've literally given you exactly what they have given me. They think the issue is to do with neighbor solicitation and pfsense not accepting it.

So in summary - I'm out of moves. I feel that if this is ever going to get resolved, and we need more info from Telstra, then I would need to ask them specific questions for them to answer (and I don't know what those questions are).
I've asked the general questions like you've already asked me which is "how do they expect a client to get a DHCPv6 PD" and their response was the email above, plus the monitoring of my control plane, and coming back to me saying its a neighbor solicitation issue with pfsense.

You should absolutely see traffic on WAN on UDP/547
That is Solicit, Advertise, Request, Reply
All I did was start that capture then edit/save Interfaces > WAN

I am reading info on how other 3rd party routers have got theirs up and running with Telstra and trying to translate that into pfsense.
Maybe you should post some of those.

@derelict Sure. Here is one https://forums.whirlpool.net.au/archive/2597579

OK so prefix-only probably translates to:
Request only an IPv6 prefix
Only request an IPv6 prefix, do not request an IPv6 addressDid you check that?

Yes - I've tried that too.

OK and what did the dhcp6c logs look like when you only enabled that and tried it?
You're going to have to be a lot more forthcoming with information. We can't test it from here. Only you can.

Here are the logs. Want another packet capture too?

Mate - really appreciate you helping me. Apologies if I am not giving enough info. I'll just assume from here on in to include logs and packet captures every time you ask me to change something. Shout out if you need more info than those things.
What just seems strange to me is this whole neighbor solicitation thing on ICMP. It doesn't seem to be able to get past that and onto UDP.

@derelict This is the only info I can get out of the Telstra router which does get a valid IPv6 address. Not sure its helpful, but thought I'd give it to you:

That doesn't show a DHCP attempt.
You might want to reset to defaults and start over.
Resetting everything related to the WAN DHCP6 should be enough but nobody knows what you've clicked to try to fix this.
-
@larrikin Well then that whirlpool link you posted is wrong because obviously it issues a WAN IP address.
-
Did you get traffic on IPv6/UDP/547 on the WAN? If that's not happening nothing is going to work.

Welcome to my confusion of the land of contradictions with the information that is out there on how Telstra IPv6 actually works :). The Telstra modem I showed you above has a WAN v6IP address. There is another Telstra modem I have where it doesn't get a WAN v6IP address. It's different per their modems.

I only get the ICMP traffic with the neighbor solicitation that you see in the packet capture. Telstra responds to my pfsense request using ICMP neighbor solicitation, but my pfsense doesn't seem to do anything with their response, so it just goes into a perpetual loop. That's the problem from Telstra's perspective.

I've done exactly that. The config I have is exactly the one you've asked me to do. I have nothing else configured. Let me know if you want screen shots. I've literally disabled everything. I've even factory reset pfsense. Then freshly did the config as per what you asked. That is the config that is currently live.
