Hello again everyone, I have a new lead which I think explains the issue. "Un-relayed" DHCPv6 traffic arrives at IPv6 address ff02::1:2 (all DHCP agents) while relayed IPv6 traffic arrives at IPv6 address ff05::1:3 (all DHCP server (site)). I used netstat -g to confirm that the older ISC DHCP server v4.3.5 (dhcpd) starts listening to both IPv6 addresses, but KEA 2.0.3 only listens to ff02::1:2. Does someone know why this is the case?

I am running the server with the "-d" flag, so I should see all available logs live, I think. /Oskar -----Original Message----- From: Kea-users <kea-users-boun...@lists.isc.org> On Behalf Of kea-users-requ...@lists.isc.org Sent: Sunday, October 29, 2023 1:00 PM To: kea-users@lists.isc.org Subject: Kea-users Digest, Vol 112, Issue 36 [Du f?r inte e-post ofta fr?n kea-users-requ...@lists.isc.org.

Have a look at the logging section in documentation. There are also a couple articles about logging on kb.isc.org. You might get some logging without logging configured but you probably want debug level logging setup to troubleshoot this problem.
