Good Evening, I’m actually using the realm based proxy routing and trying to configure a NAS IP Address based proxy routing. *_Main Problem :_* 1/ I’ve moved the line “files” before the line “suffix” in the radiusd.conf file to force the radius server to check the files before the realm usage in the login. Did I do it right ? 2/ I’ve added a test line : TestUser Client-IP-Address == 192.168.1.128/28, Proxy-To-Realm := ServerA I’ve restarted the freeradius deamon for the server to take care of the changes. --> It _does not work_ as described in the debug output : modcall[authorize]: module "files" returns notfound for request 34 3/ I’ve changed the test line to : TestUser Client-IP-Address == 192.168.1.129, Proxy-To-Realm := ServerA I’ve restarted the freeradius deamon for the server to take care of the changes. --> It _does work_ as described in the debug output : users: Matched entry TestUser at line 19 modcall[authorize]: module "files" returns ok for request 4 Could you give to me a good advise to help me ? *_Other Question : _* Do I need the same configuration in the “users”, “acct_users” and “preproxy_users” files ? Sincerely, Philippe
