Have you tried setting the “dhcp-socket-type” to “udp”? Docs indicate that if not specified, the default is “raw”. If you’re only needing DHCP on unicast (via relay), you should be able to set to “udp” which should disable reception of broadcast packets from directly connected clients.

Hi Is there a way to stop Kea from listening on multicast address , since our set up only uses relay forwarding to request for ip which is point to point. when i enable listening on global interface by default kea listens on multicast address and the number of requests received over multicast is overwhelming .
