Problem using subclasses, getting no free leases

[Holger Honert]

Hi Marcus,

what about defining a pool range such as:

subnet 192.168.8.0 netmask 255.255.255.224
{
    pool
	
    {
        range 192.168.8.11 192.168.8.100;
        option domain-name "public.local";
        option subnet-mask 255.255.255.224;
        range 192.168.8.10 192.168.8.20;
        allow members of "test";
    }
}


Kind Regards

Holger
