Debugging DHCPv6 on WAN interface

[QuisaZaderak]

Hi,

in 22.1.2_1 the option to enable debug output in DHCPv6 interface config is no longer present.
My already working configuration of running IPv6 on Starlink WAN adapter (and refreshing it by rtsol) stopped working. I do not receive any IPv6 configuration any more on this WAN port.
Even after several reboots of Startlink and OPNsense did not resolve the issue. Still only a IPv4 address on this WAN port. IPv4+IPv6 on WAN for LTE and WAN for DSL are still received.

Tried lowering the prefix hint from 56 to 64 (and back again to 56), toggled all 8 possibilities of Request only an IPv6 prefix / Send IPv6 prefix hint / Use IPv4 connectivity. No success.

I want to look into DHCPv6 communication on Starlink WAN port why it no longer receives a valid IPv6 address / prefix. How to do this without the debug setting? Only way of Packet Capture / tpcdump?
