Hi I am new in Freeradius and i am search a small help. - I receive a Radius Access request of the radius of my supplier. this Radius have the ip address 192.168.10.100 - Based on the realm, i forward the request to my customer. i want add in the process a action before sent the request to my customer. Actually i have: in proxy.conf home_server rad-auth-primaire-1.customer_realm.myrealm { type = auth ipaddr = 172.16.1.1 port = 1812 secret = password require_message_authenticator = yes response_window = 20 zombie_period = 40 status_check = status-server check_interval = 20 num_answers_to_alive = 3 } home_server_pool pool-auth.customer_realm.myrealm { type = fail-over home_server = rad-auth-primaire-1.customer_realm.myrealm home_server = rad-auth-secondaire-1.customer_realm.myrealm } realm "~(customer_realm.myrealm)" { auth_pool = pool-auth.customer_realm.myrealm nostrip } i want add this action: Before sent the access request to my customer, i want that my radius answer to the radius server of my supplier a Access-Accept with a: Tunnel-Server-Endpoint:0 = "172.17.10.250" With this information, my supplier sent the tunnel to 172.17.10.250, it's a Cisco router, when i receive the tunnel he sent a access request to my radius and i want that my radius forward the request to the radius server of my customer with a : NAS-IP-Address = 172.17.10.250 It's possible ? CPE Customer ==> My_Cisco_172.17.10.250 ==> Cisco of my Customer (replied in radius tunnel end point) I don't know what file i modify for this, policy.conf ? other ? very very new ;=) thanks for your help Olivier
