FreeRADIUS 2.1.12 as DHCPd with both static and dynamic IP-MAC accociations via

Hi all, Again a questions about FR2 as DHCP server with SQL: Is it possible to setup FR as  DHCPd on FreeBSD to a given interface or it's IP? Could I use rlm_sqlpool to store MAC-IP associations? I am trying to use an old dial-up  module (FreeNIBS) for my WiFi network, all seems to be OK,  but there is no DHCP,
