Dynamic IP assignment problem

[Mr. K]

Hi all, 

I´m starting on using freeRadius and I´m trying to use ippool to assign an
IP dynamically for different users. Using the radiusd –X option, I finally
could receive an Accept packet with an IP.

The problem is that the IP that I’m receiving is not from the pool defined
in the radius.conf file as I will try to show in the logs below.

Module: Loaded IPPOOL 
 ippool: session-db = "/usr/freeRadius/raddb/db.ippool"
 ippool: ip-index = "/usr/freeRadius/raddb/db.ipindex"
 
#### This is the definition used in the radius.conf
ippool: range-start = 10.0.10.1 IP address [10.0.10.1]
 ippool: range-stop = 10.0.10.200 IP address [10.0.10.200]
 ippool: netmask = 255.255.252.0 IP address [255.255.252.0]
 ippool: cache-size = 800
 ippool: override = yes
 ippool: maximum-timeout = 0
Module: Instantiated ippool (main_pool) 
 detail: detailfile =
"/usr/freeRadius/log/radius/radacct/%{Client-IP-Address}/reply-detail-%Y%m%d"
 detail: detailperm = 384
 detail: dirperm = 493
 detail: locking = no

Then when I when receiving the IP:
rad_recv: Access-Request packet from host 172.16.3.185:1130, id=0, length=64
        User-Name = "7875305130 at newcomm"
        User-Password = "7875305130"
        NAS-Port = 7777
  Processing the authorize section of radiusd.conf

The process of authorization ends OK, but the assigned IP is from the
original main_ippool that I have modified.

Login OK: [7875305130 at newcomm] (from client iot port 7777)

        Framed-IP-Address = 172.16.3.172
        Framed-IP-Netmask = 255.255.252.0
Finished request 0

I really don’t understand where are stored this IP from the original
configuration. Maybe I still have to change any other configuration file,
but I don`t realise where.

Thanks in advance.
