OPNsense 26.1.2 (although this was a problem on various 25xx versions)
ISC DHCPV4 (not sure this is relevant)
In order to keep my kids from using private MACs to get internet at night (I have schedules enabled), my lan DHCP scope is a /23. I have my DHCP server set to give IPs out from the second /24. That /24 is blocked in the firewall. Essentially, if a new MAC connects, it won't get internet until I make a DHCP reservation and put the IP in the first /24. This has worked for years up until a few months ago, so I believe this setup is largely irrelevant.
Sometime in the last few months, I started having issues that IPs that I manually assign an IP from the first /24 that "should" have internet, they will not have internet until the firewall is rebooted. This behavior is very odd and I don't think this is normal. Is this a normal setting that I just don't know about, or is something messed up?

My understanding is/was that those "MACs" aren't actual MACs and that this option in both ISC and KEA would prevent them flooding your DHCP Scope : https://forum.opnsense.org/index.php?topic=50536.0
But no one can tell me if this is indeed true for both and not just ISC and the KEA Documentation on the KEA website doesn't tell me a word about it either...
