No IPv6 Address on PPPoE with 24.7.11_2

[dennyo]

Hello,

I just upgraded from 24.7.9_1 to 24.7.11_2 and after that I am not getting an IPv6 WAN Address nor a delegated prefix over my PPPoE Connection. With 24.7.9_1 everything works fine.

Setting:
PPPoE Adapter, default settings
WAN Interface: ipv4: pppoe; ipv6: DHCPv6; Use IPv4 connectivity; Basic; delegation size 56; rest is all default
Tunable: net.inet6.ip6.dad_count = 0
fixed a dpinger problem long ago (https://github.com/opnsense/core/issues/6913)

After Update I can see a logfile which made me curious:
Error dhcp6c transmit failed: Permission denied
/usr/local/etc/rc.newwanipv6 also got some error messages.

The System runs virtualized so I did a Snapshot Rollback but currently 24.7.11_2 seems unusable for me.

What I tried:
Request prefix on only on/off
Send prefix hint on/off
combination of both

DHCPv6 to PPPoEv6 and back
PPPoE Compression on/off

Nothing made a difference :-(
