No remote authentication

Check if you have the iptables process running. If you do, you have a firewall.

Stop the service and see if things start working. If they do, your firewall was blocking the traffic and you will need to set up rules for that.

I am not an expert in networking, but I assume this is the command you are talking about:

ubuntu:/etc/freeradius$ sudo netstat -anpu
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
udp        0      0*                           3777/freeradius
udp        0      0  *                           3777/freeradius
udp        0      0  *                           3777/freeradius
udp        0      0  *                           3777/freeradius
