We are proxy some requests to a radius server that is outside our control. Sometimes the server is unavailable and does not respond. When it does not respond then out radius server does not respond to our lns and the lns marks our server as dead. My understanding is that by using the Post-Proxy-Type Fail method i can send a failed authentication to the lns if the proxied too radius server does not respond and avoid the lns marking my server as dead. This is what I have done: server home.tent { pre-proxy { # Insert pre-proxy rules here } post-proxy { Post-Proxy-Type Fail { detail.tent fail } } listen { type = detail filename = "${radacctdir}/detail.tent" load_factor = 10 } accounting { update control { Proxy-To-Realm := "tent.net" } } } home_server tent { type = auth+acct ipaddr = XXX.XXX.XXX.XXX port = 1645 secret = password response_window = 2 zombie_period = 5 status_check = request username = "test_user_status_check" password = "this is really secret" } As you can see I also have added the detail option to the Post-Proxy-Type Fail so that accounting packets get sent to a file if the remote server does not respond. Do I have a flaw in my syntax or is it in my logic. Thanx for any help. Mark
