Server is run in debug mode (radiusd -X) The following is entered in the clients.conf file: client erx.radius-src-ipaddr { secret = juniper nastype = other shorname = ERX1 } -------------------------------- Using netstat the server appears to be listenting on correct UDP port 1812 [root@freerad raddb]# netstat -a | grep radius udp 0 0 *:radius *:* udp 0 0 *:radius-acct *:* -------------------------------- Start Radius with : radiusd -X (debug mode) shows server listening on 1812 client erx.radius-src-ipaddr { require_message_authenticator = no secret = "juniper" nastype = "other" } ... adding new socket proxy address * port 38660 Listening on authentication address * port 1812 Listening on accounting address * port 1813 Listening on command file /usr/local/var/run/radiusd/radiusd.sock Listening on authentication address 127.0.0.1 port 18120 as server inner-tunnel Listening on proxy address * port 1814 Ready to process requests. Testing local to server works correctly but when I test from NAS (ERX) there is no output observed in the debug window (radiusd -X). I used tcpdump to confirm that packets are reaching the server. Any help would be greatly appreciated...
