Hi everybody, thanks to Daniil and Yvan who helped me, but unfortunalety, my problem still alive. First , I want to explain again what I want to do, because may be there is a missunderstanding. I have a wireless system wich need EAP and my users are allready known in a Radius system (Radius n°2) wich don't know that protocol. The idea is to use in between a freeradius (Radius n°1) wich will convert EAP-Response/Identity from Access Point and will forward Radius Access-Request without EAP message inside to my existing Radius server (Radius n°2). My problem IS NOT to manage some requests with EAP and some without. May be some of you understood that ? This weekend, i updated frreradius to the last version 2.1.7. I changed configuration files too. But problem didn't change : Radius n°2 receive EAP request that it don't know how to manage them. This is the last modifications I did : Supplicant is configuring for PEAP MSCHAPv2 (I tryied with TTLS but main problem is the same) *raddb/proxy.conf* realm jacques.net { authhost = 192.168.0.252:1812 accthost = 192.168.0.252:1813 secret = secret } *raddb/**eap.conf* peap { default_eap_type = mschapv2 copy_request_to_tunnel = yes use_tunneled_reply = yes proxy_tunneled_request_as_eap = no virtual_server = "proxy-inner-tunnel" } mschapv2 { } } *raddb/**sites-enabled/proxy-inner-tunnel* server proxy-inner-tunnel { authorize { update control { Proxy-To-Realm := "jacques.net" } } authenticate { eap } post-proxy { eap } } I have a "big" answer. When i configure an external radius server in proxy.conf . Is eap.conf is use ? Because it is like it was not. Best regards
