I can get Access-Accept but no Framed-IP-Address

26 Jan 2010

      Hi,
I fresh install freeradius ( Yes. I am newbie). I try to give IP address
for my authenticated user who use token as password. But still I don't
understand why altough  users can give access if IP is in a ip pool,
other users can't give IP address as static. What affects while user
take IP address as static and  from pool? What are the changes?

#users file:
tevfikceydeliler        Proxy-To-Realm := 10.1.1.51
                        Framed-IP-Address := 172.30.64.20,
                        Framed-IP-Netmask := 255.255.255.255
In my case user can get Access-Accept but there is no IP address
