[Kea-users] [kea-dev] kea-dhcp6 ignoring DHCPv6 messages received on a tuntap interface

[Francis Dupont]

Did you try to add an address to the interface in the kea.conf?

PPS: your tcpdump shows a link local source address which is highly
suspect to my eyes: usually tuntap requires IP routing to operate
so no link local.
