Now - go and change that client's reserved IP address and watch as the client will not pick up the change after you save it..

Did change the reservation and the client picket it up, it does work for me.
From dynamic (.102, range .100 - .199) to static mapping (.78) to another static mapping (.40). For the last change it took a minute or so after the link up on the client.

I will try applying the patches tonight when I reboot the pfsense.

No patches avail:

The one patch I found for Kea was for the plus version 24.11. I had applied it a week or so back. Made no difference in my issues last night and today.

Fix Kea failure with per-pool settings for Default or Maximum Lease Time (If this patch offers both Apply and Revert actions, do not Revert, Redmine #15332)

Bill Meeks left an informative note on my issue about significant differences between the Kea versions for CE and Plus. But even those differences didn't make Kea work for my problem. Thanks for posting on the reboot. That is the only thing I could do to fix my issue.

@KB8DOA There should be a lot. Did you update the patches package?

Restarting the DHCP Service does not help - a reboot is the only way the changes will take effect.

cat  /usr/local/etc/kea/kea-dhcp4.conf

and hit execute.

Keep te screen open, and open another pfSense GUI, and go to the DHCPv4 settings pages.

Now : compare.

Most, if not all, what is shown in the file is easy to understand.

The (your) question : what setting is present in the GUI that you can't find in the config file ?

@Gertjan

I am not saying that the conf file and GUI are different.
What I am saying is that the GUI/conf changes do not get applied until I reboot pfSense.

I have verified, and the changes I made are already in the conf file.
Also - just to clarify - I am using the default DHCP Lease time.

2 examples:

Change DNS Servers for an interface:

the devices on that interface keep renewing for weeks and are still using the old DNS Servers...
upon rebooting, all the devices will start using the new DNS Servers.

Assign Static Mapping of IP:

the device will continue to keep renewing and using the default ip address assigned from the Pool for weeks...
upon rebooting, the device will start using the Static IP Address that has been assigned to it.

Had it happen again.

After rebooting pfSense+, the DHCP server finally issued the correct IP Address to the DHCP Client.

Does anyone else want me to try something?

KB8DOA

@Ramosel

You are welcome.

I am going to start looking into going back to ISC DHCP.

Even though it is EOL, at least it is not Beta...

If you have some spare moments, run this while using ISC, and Kea :

and hit the start button.

You'll see the DHCP "client" requests in real time, the ones reaching your pfSense DHCP server, and the DHCP server answers.
