Sending the Framed-IP-Address from a module

[Romeo Mihalcea]

I got a complicated schema where my radius server needs to send the
Framed-IP-Address based on the results of a redis-db query so, I would
like to know if if the post-auth part of my default config I can do
that.

Something like (or any other solutions doing this):

        update reply {
                Framed-IP-Address := xxx.xx.xx.xx
        }

where xxx.xx.xx.xx is an ip address returned by a module.

Much appreciated.
