Hello,
I think that in case of relay, you need to specify the global IPv6 address in
DHCPv6 configuration, like this:
"interfaces": [ "em1", "em1/2001:db8::1" ]See this
documentation:https://kea.isc.org/docs/kea-guide.html#dhcp6-unicast

stumped me. I’m using Kea 1.1.0 on Ubuntu 18.04 for IPv6 only. The v4 server
is not installed. It is serving addresses for the local subnet with no
problem. I have a guest wireless network connected to an interface on my Cisco
1941 router. This router has a dhcpv6 relay destination of my Kea server.
Tcpdump on the server shows that the server is receiving relayed DHCP requests
from clients on the guest network, and the packets contain a link address which
is valid in the subnet definition in the Kea config; however the server is not
responding in any fashion to these requests. It’s as if they were not there at
all. I have tried the “relay” IPv6 address option in the relevant subnet
definition, even though it shouldn’t be necessary, but it makes no difference.
I’m sure this worked for a while but now I just can’t make it work. Here is my
