ADSL access server, freeradius and MULTI IP assignement

Hi all.

I'm trying to set up a fully operational adsl access router so i mean,
I have a cisco 7200 as access server (NAS) and a freeradius. Everythings
works fine (dynamic and one static IP assignement) exept for the multi
IP assignement (so one starting IP and a netmask). In this case the
clients authenticate but the IP is not assigned at all so they can't
access Internet. What is the problem?
This is my configuration parameters for /etc/raddb/xxxxxxx.users file:

xxxxx Auth-Type := Local,User-Password == "adsl" #not working
Framed-IP-Address = x.x.x.x,
Framed-IP-Netmask = 255.255.255.248,
Fall-Through = Yes,

xxxxx Auth-Type := Local,User-Password == "adsl" #working well
X-Ascend-Assign-IP-Pool = 3,
Fall-Through = Yes,

xxxxx Auth-Type := Local,User-Password == "adsl" #working well
Framed-IP-Address = x.x.x.x,
Fall-Through = Yes,

I'm sorry but I'm not expert at all in freeradius software, I'm a very
beginner, can you help me?

Many thanks,
Dario Maurich
