Migrating one intf to Kea DHCPv4 failing

[9axqe]

I have successfully migrated from ISC DHCPv6 to Kea DHCPv6, now I would like to now migrate to Kea DHCPv4.

My first test is, enabling Kea DHCPv4 for a single "test" interface and check it works as expected. But currently it's failing.

The same interface works without issue with ISC DHCPv4. I am simply disabling ISC v4 for this interface, then enabling it for Kea. Same Interface IP, same DHPC IP pool.

But DHCP stops working then, DHCP requests are simply not answered (I launched wireshark on the computer to check this).

The laptop is directly wired to the igb3 interface on the DEC695. Is it not supported to have Kea DHCPv4 on one interface but ISC DHCPv4 on another?

If anyone has a pointer on what I should be checking, I would be grateful.

Have you checked with "sockstat -l" to see if the DHCP ports 67/68 are bound to KEA when you tried that?
