IP Pools How ?

Hello ; New to this great mailing list and the whole linux world so please bare with me. :) Im using FreeRADIUS Version 1.1.7 with fedora core 10 and my freeradius frontend is DMA Softlabs Radius Manager. http://www.dmasoftlab.com/cont/home My clients are authenticating through distrubuted remote pppoe servers on a wireless network. I want to use freeradius Ip Pool functionality to assign dynamic public IPs to customers since my frontend doesnt support that feature. Is there a step by step approach on how to do it ? is just modyfying the radius.conf and users file is enough? Do i have to create any sql tables for this ? Thanks and greetings from Northern Cyprus
