Hello all I need to setup 2 freeradius servers for mac address authentication. My scenario is Access point send access-request to 1st freeradius server to do mac address authentication .If 1st server doesn’t have MAC Address in database ,it must send this request to 2nd server(which is freeradius server too) to find in another database. I try to config proxy.conf file in 1st server as follow home_server pri_home_server { type = auth+acct ipaddr = localhost port = 1812 secret = xxx response_window = 20 zombie_period = 40 revive_interval = 120 status_check = status-server check_interval = 30 num_answers_to_alive = 3}home_server sec_home_server { type = auth+acct ipaddr = xxx port = 1812 secret = xxx response_window = 20 zombie_period = 40 revive_interval = 120 status_check = status-server check_interval = 30 num_answers_to_alive = 3} home_server_pool auth_failover_pool { type = fail-over home_server = pri_home_server home_server = sec_home_server} realm users{ type=radius auth_pool=auth_failover_pool acct_pool=auth_failover_pool nostrip} but it doesn’t work So the question is Do I need to config proxy.conf or others files ?or other method to setup for this scenario ? Any help is appreciated. Thanks in advance.
