Alright... this is a little embarrassing. I am using amazon EC2 for the server and I completely forgot there is a firewall to manage in the EC2 management console as well. Requests go through now.

Thank you all for helping me to figure this out.

If the freeradius daemin sees nothing and is listening on the ports (netstat) and theres no firewall (iptables) then either something somewhere else on your network is blocking the RADIUS packets or your NAS config is wrong (either its AAA settings or its eg management routing )
