>>> > OK, your setup allows only specified devices into each pool - therefore any device not matching those criteria will not be able to get a lease and the server will lot "no free leases" which should really be "no leases free that I'm allowed to issue".

>> Thanks for your response! I'm not sure if you are making reference here to the intentionally defined dual subnets, or to a misconfiguration that will only allow devices with reservations to connect. If the former, the creation of two subnets is intentional, and I understand that devices will only be able to connect to one or another. If the latter, then please tell me which directive is keeping non-explicitly reserved devices from connecting. In fact, this later scenario is precisely what's occurring; devices with defined reservations are able to obtain addresses without problem, though only in the upper subnet, where *no* explicit reservations are specified.

On the same network...

subnet 192.168.1.0 netmask 255.255.255.128 {
	option routers                  192.168.1.1;
	option subnet-mask 		255.255.255.128;
	option broadcast-address 	192.168.1.127;
	...
}

subnet 192.168.1.128 netmask 255.255.255.128 {
	option routers                  192.168.1.129;
	option subnet-mask 		255.255.255.128;
	option broadcast-address 	192.168.1.255;
	...
}
