      Hi

      Setting "IPv6 Configuration Type" on the WAN interface to DHCP6 leads to the following errors every 30 minutes (from DHCP log)

      dhcp6c[81281]: dhcp6_get_options: unknown or unexpected DHCP6 option server unicast, len 16
dhcp6c[81281]: update_ia: status code for NA-0: success
...
dhcp6c[81281]: dhcp6_get_options: unknown or unexpected DHCP6 option server unicast, len 16
dhcp6c[81281]: update_ia: status code for PD-0: success

      which then leads to the restart of / issues with multiple services (at least openvpn, radvd, dnsmasq, ntp) (example from log: openvpn[25405]: SIGTERM[hard,] received, process exiting)

      Of course I'd like to provide you with more useful information but besides the dhcp6c crashing every 30 minutes and then crashing other services there is nothing abnormal (in other words IPv6 is working) and also googling for "unknown or unexpected DHCP6 option server unicast" doesn't find any results at all.
      If you can think of any useful information I could provide please let me know.
