DHCP 82 Option Controls

[Maile Halatuituia]

Hi I have this send to my FreeRadius Server from a BRAS that serves as a DHCP Server for Clients. I want to authorize my user using their phones number as send by the BRAS as the Calling-Station-Id below. I understand that I can't authenticate as this is DHCP, please correct me if I am wrong compare to PPPoE.

My Default Server Control Portion.
This is the portion I believe it is relate to this where I attach some realm in this case (prepaid.to) .
if ( &WiMAX-BS-Id ) {
                perl
                mschap
        }
        else {
        if ( &Calling-Station-Id ) {
                update request {
                &User-Name := "%{%{Stripped-User-name}:-%{User-Name}}@prepaid.to"
                }
                        ### for keyed-balance
                update control {
                        &Load-Balance-Key := "%{Calling-Station-Id}"
                }
        }
        else {
                if ( &User-Name !~ /\@/ ){
                update request {
                        &User-Name := "%{User-Name}@kalianet.to"
                }
                }
        }

I am not sure I have this as a valid start or this does something other than what I want to achieve.
My problem I can summarise on these two points.


  1.  First how can I use my Calling Station to authorize the DHCP Clients. ???
  2.  Secondly if possible to do Authentication with Calling-Station-Id before address assigned to the Customer.???
Attached is the Debug File.
