Dear Paul Jenner, It's not a bug. In case of UDP, if you bind service to all interfaces and there are 2 interfaces on the same network there is no guarantee reply packet will be sent from interface incoming packet was sent to. Because replay packet will always be sent from interface according to routing table (if there are 2 records for same network with same metrics first one will be chosen). It's expected behavior.
Program need some code to specially change binding interface in order to process request as you expect it to do. In case of FreeRADIUS it's not trivial, because interface is shared between multiple threads and changing interface binding may affect another threads. So, best solution for you is to review your network configuration. --Friday, February 7, 2003, 7:00:29 PM, you wrote to [EMAIL PROTECTED]: PJ> Hi.
