ipV6 with 24.1.10_3 issues

[emmann]

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:

Any hints are super appreciated. Thanks

What happens if you check the option  "Request only an IPv6 prefix" which skips requesting a WAN address.
Are you at least receiving a prefix then?

[emmann]

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.
