I get a prefix, it is shown, the LAN interface assigns the ip, but it gets reset a few seconds later.
Also if I request a WAN ipv6 address it still works, I get the address and prefix, but same behavior.

Hello all,

Just signed up because this thing bugged me from some weeks now, and scouring the whole forum could not give an answer/solution to it.

I have problems with ipv6, as I see more people have with the 24 train, but in my case there is not ipv6 received at all(or it gets an ip and it gets wiped after a few seconds)

The wan setup is as always
- pppoev4
- dhcpv6 with ipv4 connectivity, prefix delegation /56, send prefix hint.
-lan with track interface

I have added all rules possible to allow any, even disabled filtering. Tried different tracks of 24.x, its present on all. The same settings are working perfectly well on a pfsense instance(so it can't se from provider).

The following logs can be seen:
