Apparently your firewall is inactive. For the sake of conscience, issue the following command: sudo iptables -F This will flush all firewall rules, including other tables. Make sure radiusd.conf "listen_address" param is equal to "*". This ensures freerarius will bind in all available IP addresses (0.0.0.0). Clayton A.

Again, I am not very good with networking, but I assume there's no active firewall on my server after running those 2 commands:
ubuntu:~$ sudo iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination
Chain FORWARD (policy ACCEPT) target prot opt source destination
Chain OUTPUT (policy ACCEPT) target prot opt source destination
ubuntu:~$ sudo ufw status Status: inactive
Am I correct?
Thanks everyone for trying to help by the way. I just joined the mailing list and am happy to see it so active.

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 0 127.0.0.1:18120 0.0.0.0:* 3777/freeradius udp 0 0 0.0.0.0:1812 0.0.0.0:* 3777/freeradius udp 0 0 0.0.0.0:1813 0.0.0.0:* 3777/freeradius udp 0 0 0.0.0.0:1814 0.0.0.0:* 3777/freeradius udp 0 0 0.0.0.0:68 0.0.0.0:* 459/dhclient3

Hi,
but the server debug mode (server side) does not react at all and stay in the waiting for requests state, while the client gets its requests to timeout.
..so the server doesnt receive the packet at all? in that case check your firewalls - eg the server firewall...ensure UDP 1812 is allowed
