Hi Alan,
What does Kea have in the DHCPv6 log for this request? It may help to increase
verbosity. Since this is subnet id 11, I assume you have other subnets that are
already configured and working; is this accurate?

Looking for suggestions - tshark shows forwarded dhcpv6 requests being
received, however they're being ignored:
