When will IPv6 prefix-delegation on opnsense work again?

[Bytechanger]

Hi,

I run the OPNSense behind a FritzBox.
The FritzBox delegates ipv6 to OPNSense.
This worked wonderfully up until version 24.7.5_3.

Since then (24.7.11_2) the FritzBox stopped delegating ipv6-networks to the OPNSense!
However, the WAN connection receives an ipv6 address from the FB network.

So after Verson 24.7.5_3 ipv6-Delegation is broken!
So I stuck on Version 24.7.5_3!!

I'm also running OPNsense behind a FritzBox and I don't see any problems with PD.
Maybe there's something specific with your config that causes problems?

What could the problem?
Running under 24.7.5_3 but above not?
When I restore Backup from this version in Proxmox it runs well immediately.

Same config, starting update, then it doesnt work anymore!
Restore Backup from 30 minutes ago, old version, runs well and gets ipv6 pd fast.

@troplin:
Did you get an ipv6 prefix? Wich size?
Mine is 60
(because FritzBox get its own networks for guest automatic).

Hey,

Does it work for the rest of you?
I have my OPNSense behind the Fritzbox.
It is connected as an exposed host.
 
In the FritzBox I have -Assign DNS server, prefix (IA_PD) and IPv6 address (IA_NA)- and -Also allow IPv6 prefixes that other IPv6 routers in the home network b- activated.
My ISP send the FritzBox /56 networks for delegation.
In OPNSense I set delegation size to /60.

This works in the old OPNSense version.
At the new versions, I don't get any networks for delegation from the Fritzbox.

I tried different things:
-Request Prefix Hint only ON/OFF, etc.
Are there any logs I could include here?

Need help please

Are there any logs I could include here?

dhcp6c goes to the system log (System -> Log files -> General). You might want to set Interfaces -> Settings -> IPv6 DHCP -> Log level to at least Info, if not Debug.
