Hi, Could you please fix following problems: Main configuration: # (1) Define two productioni/test home server(s). # Production home servers # Test home server. home_server wapgtw.test.system { type = acct ipaddr = x.x.x.x port = 1813 secret = ... status_check = none zombie_period = 40 revive_interval = 120 } # Put all of the servers into a pool. home_server_pool wapgtw.test.system { type = fail-over home_server = wapgtw.test.system } # (2) Define a realm for these home servers. # It should NOT be used as part of normal proxying decisions! realm wapgtw.test.system { acct_pool = wapgtw.test.system } # (3) Proxy configuration needs to be outside virtual server configuration listen { ipaddr = * port = 0 type = proxy } # (4) Global configuration for accounting listen { ipaddr = * port = 2813 type = acct virtual_server = wapgtw.test.system } # (5) Define accepted client(s) client 10.8.251.153 { secret = xxx shortname = xxx } # (6) Define a virtual server to handle production pre/post-proxy re-writing server wapgtw.test.system { preacct { # Insert preacct rules here preprocess linelog update control { Proxy-To-Realm := wapgtw.production.system } update reply { Fall-Through := No } update request { Called-Station-Id := "%{Called-Station-Id}.%{3GPP-SGSN-Address}" } } } radiusd: FreeRADIUS Version 3.0.0, for host x86_64-unknown-linux-gnu, built on May 2 2013 at 09:34:02 Copyright (C) 1999-2013 The FreeRADIUS server project and contributors.
