Hi there,
I have set up dnsmasq as my DHCP server on my OPNsense 25.1.12. I added a range 10.10.10.100 - 10.10.10.200 for interface LAN with a couple of hosts with reservations. Since the amount of devices is increasing, I wanted to create some new subnets 10.10.20.0/24 and 10.10.30.0/0 and put some of the devices there but devices without a reservation should still get their IPs from the 10.10.10.0/24 pool. However, when I add a host to another subnet, it will still get an IP from the 10.10.10.0/24 subnet, ignoring the reservation.

How can I get dnsmasq to assign the IP from another subnet if a reservation like that exists?
TIA
