Hi! I have a problem here and would appreciate any enlightenment and
example configuration file.

I am currently testing a GPRS RAS.  It can be configured to assign IP
address dynamically with an IP pool.  

However, if it is configured to assign the IP address dynamically, it will
not send accounting start and stop packet to the Radius server :-(

But if we let Radius server assigns IP address dynamically using AuthBy
DYNADDRESS and AddressAllocator SQL, then the GPRS RAS will be able to
send accounting start and stop packets.  Wierd but that is what the
vendors told me how it should work for their RAS.

However, in our testing with the above setup, we found that the IP address
never get deallocated when the user disconnect.  From the trace 4 debug,
we found that the GPRS RAS does not send the Framed-IP-Address attribute
in the accounting stop packet.

Looking at the source code, we realise that Radiator needs the
Framed-IP-Address attribute in the accounting stop packet in order to
deallocate the used IP address.

How can we configure radiator to work with the GPRS RAS in this case?

In addition, We need to configure radiator to authenticate against an
external SQL Oracle database.  On top of that, the radius has to proxy the
authentication request to at least two different Radius server for the
realm "abc.com.sg" and "xyz.com.sg"

How can we configure Radiator to handle all of the different types of
authentication method as described above and at the same time allocate IP
address dynamically for every authentication requests?

Thanks for any help.
