Hi, I have stil the same problem since a week and I don't understand why. Probably because I discover freeradius product, i did a basic error for somebody who know it. I reinstall Debian in the last stable version, i reinstall freeradius after that and the problem is exactly the same . In attach files, you'll find result of compiling/make, raddb configurations files and debug file when i start radiusd and when EAP response is done from radius client This is what I want to do do for those who don't know : I use eap to authenticate Wireless users on an radius server wich don't know EAP protocol. It seems that is possible to do that using a proxy freeradius. The architecture should be : Access Point as a NAS Freeradius as a proxy Radius server without EAP 192.168.0.250 192.168.0.128 192.168.0.252 The idea is to convert an EAP Response/Identity to a radius Access-Request without EAP inside As the first radius i use freeradius Version 2.1.7 As the second one, i use IAS (just to test, but in the final configuration, it will not) I modified these files: eap.conf (peap function), proxy.conf (add realm jacques.net) clients.conf (add 192.168.0.250) sites-enabled/proxy-inner.conf (modify Proxy-to-Realm) sites-enabled/default (comment suffix) remove enabled/proxy-inner.conf Nothing else ! I hope somebody could help me. Jacques
