FreeRadius Package

[craibo]

I am looking to use FreeRadius on my pfSense setup but i need to know a few things first:

I need 3 functions at the moment i have 2of them using captive portal but really need the 3rd:
-1 Account Logon with no concurrent logons
-2 Disable Account on Expire Time reached.
-3 Disable Account bandwidth limit reached.

Can anyone help me out with this?? or Is there a link where i can find the details about FreeRadius??

Thanks
