I think you need to analyse more the accounting request because the MAC and IP address would be different. Check the attributes framedipaddress and calledstationid in Accountig request.

I have great problems with duplicate sessions! ~2500 online users, accounting per minute, 25 db socket limit for radius daemon. Nas port id, accstoptime, session id, inputoctets, outputoctets is same in duplicate sessions. But most duplicate sessions only have difference with acctstarttime (1 second difference) Any ideas? Thanks! _________________________________________________________________ ¿Aún sin la última versión de Internet Explorer 8? ¡Actualízate gratis! http://www.vivelive.com/internetexplorer8
