Hello All 

Just to let you know that i finally find the solution to setup a fixed IP
into an l2tp tunnel for my DSL subscribers

I needed to tell Radius to send the fixed Framed IP address in the
access-req packet by adding the following to my cisco config:

radius-server attribute 8 include-in-access-req

Hope this will help someone who will face the same problem

Is the IP address in a valid range configured on the NAS?

A Cisco will not assign an IP address that it is not configured 
to handle. It seems to me we used eigrp to handle the "static" 
ip address networks for our NAS servers.
