That looks very similar to my setup which is working. Are you sure the kea service is not listening on port 8000? One way to check would be with "lsof -i -P| grep kea-dhcp" and look for a line showing the hostname:8000 (LISTEN).
If the service is listening, then perhaps there is a firewall blocking incoming traffic to port 8000? --Dan On Tue, Mar 22, 2022 at 6:53 AM Weisteen Per <[email protected]> wrote: > Hi, I've set up a HA Hot-Standby config according to docs but I can't > figure out why the servers doesn't listen on port 8000. > I thought that was the port configured for heartbeat.
