Radius Incoming Packet of Disconnection problem

Hello all,
I want to disconnect a PPPoE client connected to PPPoE server on MT using Packet of Disconnection.

To do this on linux box I use radclient application:
echo “User-name:=name”|/usr/bin/radclient -x 172.16.50.1:3799 disconnect pass

but on MT PPPoE server client is not disconnected. In PPPoE server log on MT i have:
“received remote request from 172.16.40.2:36105 with unknown address, dropping”

For sure RADIUS incoming requests are enabled, port is 3799
MT version is 4.5 or 4.6

Please help!

maybe enable ‘debug’ log for that topic and see the details?..

it is debug log, no more information.

I resolved the problem.

The IP address of machine originating Disconnect Request was different then Radius Server IP Address configured in MT.
Disconnect Requests packages sent using radclient s/w shall have the same src IP as Radius IP configured in MT.

On MT in radius debug log I still have some errors, but client is properly disconnected uppon request.

BTW. Does anybody know if or when MT developers are planning to support COA request?
