(RADIATOR) Alcatel SMC proxy radius -->Radiator issue (fwd)

[Abel Lucano]

Hi all,
I'm  trying to debug the following:
One proxy-radius (Alcatel-SMC) that forwarding radius authentication and
accounting packets to Radiator.

The whole conversation is configured to use 1645/1646 ports.

When Alcatel-SMC's proxy radius  send  access-request to Radiator
this latter sees the packet coming from 1800 or 4248 port(?); radiator
return this request from 1645 to 1800 or 4248 port.

The SMC side claims that they just are receiving from Radiator the
Proxy-State (33 binary) attribute but they cannot see basic attributes 6 and
7 (Service-Type and Framed-Protocol), and then the ppp connnection drops.

The basic <Handler> includes "DefaultReply" too and the rest is very basic
working configuration talking with other systems

<AuthBy FILE>
      Identifier DBcustomer
      Filename %D/db/users-customer
      DefaultReply Service-Type=Framed-User,Framed-Protocol=PPP
      RejectEmptyPassword
      DefaultSimultaneousUse 1
</AuthBy>


Somebody has seen this kind of problems? (I've not found it searching the
list archives )


I'm including a tcpdump extract of the basic conversation
(sorry for the XXs, YYs and ZZs; i'm doing a consulting job to others and
they've not authorized me to show their data)

Thanks in advance,
