rlm_chap: Setting 'Auth-Type := CHAP' ... rad_recv: Accounting-Request packet from host 172.17.7.214:32786, id=7, length=735 Received Accounting-Request packet from 172.17.7.214 with invalid signature! (Shared secret is incorrect.) Dropping packet without response. Finished request 3
The shared key configured is one per node in both the radius and the PDSN; so it is difficult for me to understand this behavior. Is there any configuration missing?
No.
Is it possible that the freeradius server is not checking shared key when sending the access-request message to it’s destination and checking the key while processing the accounting-request?
No. You are doing chap authentication so there is nothing for wrong shared secret to mess up. It is wrong for authentication too. Send a pap request and see what happens. Ivan Kalik Kalik Informatika ISP
