Hello, I desperately need your help. I am noob with FreeRadius so please guide me what i am doing wrong. My point is using freeradius as a Proxy. Because we already have a PAP supported Radius, so i want to do eap auth part on freeradius and then Proxy the Access-request to our own Radius. We are trying 802.1x authantication. According to my readings i did below steps : 1 . Edit clients.conf for my mobile devices to Access freeradius client nevotek { ipaddr = 213.74.143.140 secret = testing1234 } 2. add home_server in proxy.conf home_server IAS { ipaddr = 192.168.0.252 port = 1812 type = "auth" secret = "secret" response_window = 20 max_outstanding = 65536 } home_server_pool jack_pool { type = fail-over home_server = IAS } realm nevotek { auth_pool = jack_pool nostirp } 3. edit eap.cof default_eap_type = ttls and in ttls function : ttls { default_eap_type = md5 copy_request_to_tunnel = no use_tunneled_reply = yes proxy_tunneled_request_as_eap = no virtual_server = "proxy-inner-tunnel" } 4. prepare Proxy.config soft link for sites-enabled, added nevotek in proxy-inner-tunnel: server proxy-inner-tunnel { authorize { update control { Proxy-To-Realm := "nevotek" } } authenticate { eap } post-proxy { eap } } 5. disabled "suffix" part in sites-enabled/default But no chance. Also android and IOS devices has different behaviors. Here is the output of IOS device : (2) Received Access-Request Id 216 from 213.74.143.148:19733 to 10.0.0.4:1812 length 311 (2) User-Name = "iosuser2@nevotek.com" (2) Chargeable-User-Identity = 0x00 (2) Operator-Name = "1nevotek.com" (2) Location-Capable = Civic-Location (2) Calling-Station-Id = "74-8d-08-b1-f2-17" (2) Called-Station-Id = "58-f3-9c-43-52-a0:Nevotek" (2) NAS-Port = 4 (2) Cisco-AVPair = "audit-session-id=0a0102e1000001205fbba08c" (2) Acct-Session-Id = "5fbba08c/74:8d:08:b1:f2:17/352" (2) NAS-IP-Address = 10.1.2.225 (2) NAS-Identifier = "aa5a6c45-b2c2-436b-90da-0ed2031" (2) Airespace-Wlan-Id = 7 (2) Service-Type = Framed-User (2) Framed-MTU = 1300 (2) NAS-Port-Type = Wireless-802.11 (2) EAP-Message = 0x020300061500 (2) State = 0xca8e79cacb8d6ce3fd1d37ee8f32d170 (2) Message-Authenticator = 0xc7b01c5b471b2eb70578f1dc7ed6e7ea (2) session-state: No cached attributes (2) #
