Hi together, did anyone get this working? I'm trying exactly the same and get the same error.

In the host running Kea, I have two different IPv6 addresses: 2a00:xxxx::3, assigned to eth0 and 2a00:xxxx::1:3, assigned to the loopback interface. My DHCPv6 relay (2a00:xxxx:3::63) forwards requests to the 2a00:xxxx::1:3 address, via the load balancer. When I have "eth0/2a00:xxxx::3" and "lo/2a00:xxxx::1:3" in the interfaces-config section of my Kea configuration, Kea is answering the requests, but with the IP address of eth0, instead of the IP address of lo, which was the destination of the request. 22:21:27.051056 IP6 2a00:xxxx:3::63.546 > 2a00:xxxx::1:3.547: dhcp6 relay-fwd 22:21:27.051550 IP6 2a00:xxxx::3.547 > 2a00:xxxx:3::63.547: dhcp6 relay-reply 22:21:35.133247 IP6 2a00:xxxx:3::63.546 > 2a00:xxxx::1:3.547: dhcp6 relay-fwd 22:21:35.133832 IP6 2a00:xxxx::3.547 > 2a00:xxxx:3::63.547: dhcp6 relay-reply I have also tried removing the eth0 entry from the interfaces-config option, but that made things even worse, as now I get an error in the logs: Jun 22 23:10:49 hostname kea-dhcp6[15658]: ERROR DHCP6_PACKET_SEND_FAIL failed to send DHCPv6 packet: Interface eth0/2 does not have any suitable IPv6 sockets open. Jun 22 23:10:51 hostname kea-dhcp6[15658]: ERROR DHCP6_PACKET_SEND_FAIL failed to send DHCPv6 packet: Interface eth0/2 does not have any suitable IPv6 sockets open. Does Kea have an option to define the source address for outgoing packets or is there a way to achieve what I am trying to do?
