IPv6 Track Interface not getting IPv6
-
Another important point:
When I originally configured LAN IPv6 to "Track Interface", in pfSense 2.4.4-p3, and it didn't get an IPv6 address until I released and renewed the WAN โ that was using a different Internet provider. I was using Internode, with the WAN being PPPoE with VLAN tagging. Then when I switched Internet provider to Aussie Broadband, I had the same issue, but that uses IPoE instead.
Since I've had the same issue with two different Internet providers, and with both PPPoE and IPoE, that makes it more likely that this is a pfSense issue, not an issue with a particular Internet provider.

This might also be relevant:

I do have a Virtual IPv6 address on my WAN (because my Internet provider (Aussie Broadband) appears to have broken routing on the IPv6 address that it assigns to my router WAN via DHCPv6).
-
If it's the same as I experienced, I just manually added the ISP's prefix on the Router Advertisement. For some reason, pfSense stops automatically doing that, when you add a ULA prefix. However, I don't think that's your issue, as I don't recall you mentioning ULA before. I'm on a cable modem, so I can't help with PPPoE or IPoE.

Would really like to know how you've got IPv6 working with ABB.

So, you must work on the LAN Down Under.
This was sent to me when the movie was still relatively recent.

Then there's the network song This LAN is Your LAN.

I've got 2.4.5-p1 running now. Today I switched the power off and back on. When the NBN device and the router restarted, all the IPv6 addresses were assigned properly. So that's a good improvement!
Other than the pfSense upgrade to 2.4.5-p1, I haven't changed any configuration. So maybe it's an improvement in 2.4.5-p1. But, I can't say for sure, because it's possible my Internet provider has made some configuration changes which improved it.

Make sure you have Do not allow PD/Address release on the WAN page set.

A comment on Whirlpool says:
A lot of routers use the WIDE-DHCPV6 package. And many of them have not incorporated the patch listed below. Without the patch, if the DHCP client gets a response that it wasn't expecting, it just gives up and stops trying.
โ Add patch 0018 to ignore advertise messages with none of requested data and missed status codes.

Does pfSense use the WIDE-DHCPV6 client? If so, does it incorporate this patch?

@JKnott said in IPv6 Track Interface not getting IPv6:
Make sure you have Do not allow PD/Address release on the WAN page set.
Is this generic advice, or advice tuned to my Internet provider (Aussie Broadband)?
If it's generic advice, why is Do not allow PD/Address release a user option?
-
its there, on the wan interface page
Its not tuned to aussies :)(but its not that important, since this is meaningful only when interfaces close gracefully.
On a power outage, line disconnection etc, you never get the time to send such things anyways)
And isp's often don't really care and always issue a new prefix upon reconnection -
I'm in Canada, so it's not an Aussie thing. As for why it's there, previously it wasn't and the prefix would frequently change. I suppose there is a reason why someone would want to always release the prefix, but I don't know what that is, other than perhaps changing ISP or something.
