Proxying CoA

15 Dec 2010

      Hello,

I'm trying to figure out how to proxy CoA packets. I have read through a
similar thread on this list (
http://lists.freeradius.org/mailman/htdig/freeradius-users/2010-July/msg0033...
),
but somehow I cannot get it to work.

My setup is the following:

In my proxy.conf:

home_server nas_coa {
    type = coa
    ipaddr = 10.0.0.2
    port = 3799
    coa {
        irt = 2
        mrt = 16
        mrc = 5
        mrd = 30
    }
    secret = testing123
}
home_server_pool to_coa_nas {
    home_server = nas_coa
}

I have updated the sites-enabled/coa to look as below:

listen {
        type = coa
        ipaddr = *
        port = 3799
        server = coa
}

server coa {
        recv-coa {
            update control {
                Home-Server-Pool := "to_coa_nas"
            }
        }
        send-coa {
                #  Sample module.
                ok
        }
}

When I'm sending a Disconnect packet, I get the following:

Wed Dec 15 12:06:41 2010 : Info: Ready to process requests.
rad_recv: Disconnect-Request packet from host 127.0.0.1 port 56343, id=51,

NAS-IP-Address = 10.0.0.2

Wed Dec 15 12:06:43 2010 : Info: } # server coa
Sending Disconnect-ACK of id 51 to 127.0.0.1 port 56343

Clearly I am missing something obvious, but I cannot find what it is.
Any idea?

Thanks,
tripy
