IPV6 setup problem

[opensensical]

I have two separate WAN interfaces set to TRACK INTERFACE for IPV6 but I can only set 0 as the PREFIX ID for one of them.
I also wanted to set the LAN to TRACK INTERFACE but can't for the same reason.
How do I get around this?

WAN cannot be set to "track". Your internal interfaces track the WAN.

Thanks.
I reverted to IPV6 CONFIG TYPE = DNCPV6 for both WANs and the LAN.
All gateways show UP, but I am still not being issued IPV6s.
I think I need to set ROUTER ADVERTISEMENTS to ASSISTED but ROUTER ADV doesn't show if TRACK INTERFACES is not used.
I can't use TRACK INTERFACE on the LAN because this is a dual-WAN system and I can only assign one WAN as the parent.
How do I get around that?

Choose one, NPTv6 the other one.

Thanks.
I read the blog but could not understand as it was way over my head.
Please provide instructions on how to use NPTV6.
I have read several forum entries on how to try to get multi-WAN IPV6 working and found conflicting information and insufficient detail.
There does not appear to be a simple straightforward approach.
If a detailed tutorial doesn't exist, this task appears to be in the too-hard category for me and I may have to return this Protectli box and go back to my ignorance-is-bliss TP-LINK/Omada setup.
I have the interfaces, firewall rules, and gateway groups set up.
IPV4 works but IPV6 won't flow.

Multi-WAN is quite complicated. Multi-WAN with IPv6 is even more complicated. Did your TP-Link/Omada setup support it?

In your earlier posts, you weren't even sure if your ISPs provide IPv6 at all. I'd suggest getting it working with one ISP first (or maybe you have, and I missed it?), then the other ISP, then worry about multi-WAN.

Multi-WAN with opnsense is actually quite simple. IPv6 Multi-WAN is broken on a design level, nothing to do with the actual firewall you use.
