Hi all,

I would use freeradius like proxy radius. I have used freeradius like radius.
this is my lab:
STEP1: OK without freeradius
to start before FreeRadius, i do my radius config's cisco router and my Windows NPS radius config.
my client 172.25.0.11 == SSH => 172.25.0.1 (cisco) ==radius=> 172.25.0.5 (MS-NPS)
perfect the process work in PAP, i'm connected on router.

STEP2: KO with freeradius proxy
between router and MS-NPS : i add DMZ freeradius proxy
my client 172.25.0.11 == SSH => 172.30.0.129 (cisco) ==radius=> 172.30.0.133 (freeradius) ==radius=> 172.25.0.5 (MS-NPS)
sure i have changed ip client in conf ... but the problem is not here
sure i have not firewal ..
i placed tcpdump and wireshark and i discovered no packet comes out of freeradius.

Then i read wiki doc etc, i re-complied with last stable version and always same problem.
So i think i missed a few things, i touched nothing, just add line in proxy.conf and clients.conf
Is this normal in proxy mode we : ++[pap] = noop ?

another idea?

this is my log:
