Configuring the DHCP module to forward request to another Radius server.

[Fabrice-externe SEGURA]

Hi.

I'm trying to use Freeradius 2.2.0 to catch DHCP request on a local 
network (a specific interface and physical network of my machine), and 
forward it to another radius server (through another interface), using the 
radius protocol, to get authorized, and get the IP address to respond with 
to the DHCP request.

I managed to successfully install freeradius, the DHCP module listens and 
interpret properly incoming requests (and performs properly some attribute 
rewrites), but I can't find out what line(s) I should put in the "dhcp 
DHCP-Discover" section of dhcp.conf, to turn the incoming DHCP request 
into an outgoing radius request to get IP address and authorization from 
the other radius server (basically, do the proxy job !).  I see that there 
is an example to get authorization and IP allocation  with "mac2ip" 
locally, based on a file, but not how to trigger the forwarding of a new 
request.

Any advice / idea ?
