FreeBSD PPPoE server and IP Conflict

[Gloomy Group]

Hi list,


   I have setup freebsd pppoe server in 6.0. My ppp.conf server is as 
follows. Problem I have been facing is server assigns the same ip address to 
the two different clients and the clients IP get conflicted.
  I have followed WARTA project papers to do the bandwidth shaping for pppoe 
server (http://www.hpi.net/whitepapers/warta/)

                     Can anybody tell my why freebsd pppoe server assign to 
same ip address for different clients.
      Like when user "abc" connect he get 192.168.2.10 IP and when another 
user connect at the same time he also gets the same ip address i.e. 
192.168.2.10. Any suggestion for freebsd pppoe server with radius 
authentication.

default:
enable lqr
set lqrperiod 5
enable echo
enable lqr echo
enable pap
#allow users
allow mode direct
set mru 1480
set mtu 1480
set timeout 7200
set speed sync
set ifaddr 202.xx.xx.xxx 202.xx.xx.1-202.xx.xx.254
set radius /etc/radius.conf
accept dns
