Hi. Sorry for some errors in former mails. "Yes" parameter is the right one. Once i set this i obtain what i want: it works! I had misunderstood what parameter yes/no would have changed on setting. I already attach log file with *yes* setting. *So problem has been solved! :-)* Anyway . . . I see something strange in part of it: *address 172.16.68.10* I explain my configuration: a. remote NAS USG100 with publicIP 89.aa.bb.cc. LAN IP is 172.16.68.253 gateway for 172.16.68.0/24 network. it holds iformations about all AAA servers. b. my freeradius (with mysql) is behind a router (public IP 79.ss.dd.ss) that forwards 1812/1813 UDP to WAN Iface of my Fedora Server. Now . . . *172.16.68.10 is* the IP address of a Win2003 Server with WinRadius (MS Access DB) on. 172.16.68.16 is client i reach via SSL tunnel. From this one i, thru WEBLogIN (useraware of USG100), i provide username/password stored in my mysql server and authentication goes fine with freeradius. Why does it reports informations about other AAA servers? Is it an error of USG? Thanks in advance! Little abstracts about radiusd -x Setting . ... *readclients = yes* in /usr/local/etc/raddb/sql.conf, running #radiusd -X User-Name = "cactus" User-Password = "barilotto" NAS-IP-Address = 172.16.68.10 NAS-Identifier = "weblogin" NAS-Port = 15330 NAS-Port-Type = Virtual Service-Type = Authenticate-Only Calling-Station-Id = "172.16.68.16"
