Hi all, I've wirte about this problem another time here http://lists.freeradius.org/pipermail/freeradius-users/2006-October/057153.h... . The core of this problem is an error that returns with chillispot when I authenticate a client with WPA-EAP. .............................. chillispot[15816]: radius.c: 1634: Received unknown radius packet 11! chillispot[15816]: chilli.c: 4148: radius_proxy_ind() failed! ............................. I've seen the source code of radius.h in chilli at line 73, and I've seen that the packet 11 is RADIUS_CODE_ACCESS_CHALLENGE , so I've thinked that there is an error in EAP authentication. Someone has ideas about this problem? I must solve it . Thank you very much. Best regards. Giusy
