[Kea-users] kea-dhcp4 server in hybrid environment (dhcp-socket-type raw vs udp)

[Bogdan Veringioiu]

Hello,

I have recently migrated isc-dhcp-server to kea-dhcp4 (debian trixie).
After doing this I realized that I could not run kea the way I used to run isc, meaning:
- Local clients (directly connected, same lan), this works fine with the default dhcp-socket-type = raw
- Relayed clients (routed networks or clients connected over vpn tunnels) work fine with dhcp-socket-type = udp
- Hybrid environments where kea should manage subnets with directly connected clients and routed subnets (relays) simply do not work. Kea needs to have either raw or udp for dhcp-socket-type.

All 3 above scenarios used to work fine with isc with a single unified config. The way I understand it, scenario 3 is not possible with Kea.
Can you please confirm this, or advise how can I use kea as a drop in replacement for isc ?

I am working on a solution to run 2 kea instances, but it complicates things.

Thank you very much
