[Kea-users] Advice for reconfigured reservations when implementing VLANs

[Rick Frey]

Ad David suggested, getting a packet capture will help you determine if the discover packets are reaching your Kea DHCP server when not using a DHCP relay on your pFsense firewall.  On the surface it would appear that your Kea host is not seeing the broadcast packets on the three VLANs since you mention Kea “somewhat” works when using your DHCP relay.

The most recent version of pfsense also includes the latest stable Kea 2.4.1 version.  Not sure of your requirements, but you may want to consider using the Kea DHCP server on your pfsense gateway/firewall to simplify setup.  Note that pfsense has not implemented means to to configure all Kea features yet, but if you’re not using things such as DDNS updates from Kea, the pfsense version may suit your needs (and it’s more current than version you’re currently running).
