[Kea-users] KEA not send a NAK when request ip is out of scope
I got some problems with DHCP requests.
Computer logs on wifi with host login and is assigned to vlan 200 (10.28.0.0/23)
User logs into computer an reauthenticate on wifi and is assigned to vlan 201 (10.28.2.0/23)
Windows 10 sends a DHCP request for the ip address on vlan 200.
KEA sends a NAK, as the requested ip is not in scope.
Windows sends DHCP discover and so forth.
What we see is that KEA never sends the NAK, but sees the REQUEST packet as a bad packet, and then discards it.
How can I get KEA to send a NAK?
I’ve tried this with 1.3 and 1.5
