KeaDHCP dynamic DHCP question

[stauf]

Well good to know.  I was going to try to turn on Automatic Discovery and see if I could find a rogue ARP request on my network causing OpnSense to mis-behave like this, but, for now, I think I am good just leaving it off.  I, personally, don't really Automatic Discovery and it appears it does more harm than good at the moment.  Thanks for checking into it.

Same issue here w/ OPNsense 26.1.4. ICS-DHCP is not installed anymore and DNSmask DHCP is disabled, so only KEA is running.
The DHCP range is going from .200-.249. All IP adresses in the DHCP range AND all unused IP addresses outside the DHCP range are blocked, even for inactive clients w/ fixed leases.
Effectively there is no chance for a client to obtain an IP address at the moment.
This is causing some trouble.

Is there a workaround or a fix in the near future?
If not, I need to get back to ICS or DNSmask DHCP for the time beeing.

The installation was a fresh ISO 26.1.2 installation.

I assume it would make sense to check the KEA logs then why it assigns these leases?
