dhcp6c doesn't seems to start

[iv4nd1]

Hello,

I have installed the latest OPNSense version 23.1.11 and dhcpc6 doesn't seem to start when I configure DHCPv6 Prefix delegation on my WAN interface.

Please find the logs bellow :

This configuration worked fine on older OPNSense versions.

Solved, this was an issue with some undocumented configuration requirements for IPv6 from the Datacenter provider.
