Hi, I want to configure a proxy radius server and the username doesn't have any realm, just like 'tom'. So I configure realm NULL section in proxy.conf file, but it doesn't work, the error message in radiusd terminal when redius server received the accounting message: Proxying request 0 to home server 218.83.175.155 port 1813 The message can't be proxy to myProxyPool_1, I don't understand why the home server become 218.83.175.155. Can anybody help me? How to configure it ? proxy.conf file: #home server 1 home_server myProxyServer_1 { type = auth+acct ipaddr = 192.168.1.111 port = 1812 secret = testing123 require_message_authenticator = no response_window = 20 zombie_period = 40 revive_interval = 120 status_check = status-server check_interval = 10 num_answers_to_alive = 3 coa { irt = 2 mrt = 16 mrc = 5 mrd = 30 } } #home server 2 home_server myProxyServer_2 { type = auth+acct virtual_server = localserver } # home server pool 1 home_server_pool myProxyPool_1{ type = fail-over home_server = myProxyServer_1 home_server = myProxyServer_2 } #realm realm chuanwei.com { auth_pool = myProxyPool_1 acct_pool = myProxyPool_1 nostrip } realm NULL { authhost = myProxyPool_1 accthost = myProxyPool_1 secret = testing123 } Freddy
