Kea DHCP bug in 2.8.1...?

[wolfsden3]

Hi All,

2.8.1-RELEASE (amd64)
built on Fri Oct 24 11:53:00 EDT 2025
FreeBSD 15.0-CURRENT

In Kea DHCP on a 2.8.1 with patches applied per the patch package I had some DHCP clients marked as "down" with the black arrow. These are wifi based grow lights.

Firewall Kea DHCP:  down
AP:  up and connected
AP Controller:  up and connected
PC ping to grow light IP:  ping successful and steady

The only thing not properly representing the status was the Kea DHCP server list. I flipped back to the ISC DHCP (deprecated) and rebooted the AP's to force re-connections by all the lights (about 470 or so lights on 12 AP's no biggie).

Note also that I had some this similar thing using Kea DHCP but there was no change in the "down" black arrow on some hosts but with ICS DHCP it worked as expected showing green up arrows.

You wouldn't think this was a big deal because the device could network, assuming it could get online, etc but I don't really know what IP settings the lights had. For example:

Did it have just an IP but no DNS or gateway? No gateway or DNS = no Internet and that would be why the light was "down" and unresponsive to the app controlling it. This makes me think that there's a bug I'm unaware of in Kea DHCP. Some stuff is coming back online but we're still working through it.

I don't know if this is related but because some stuff is coming back online it would seem like it is. It's the only thing we've changed in the stack.

Any insight would be helpful!

Thanks.
