If "radiusd -X" isn't reporting *anything*, then it's not reaching 
FreeRADIUS, which means some part of the network stack is dropping it.

If you're sure your iptables are correct, google "linux log martians" 
and "linux rp filter". RHEL6 has different defaults to previous RHEL 
versions in this regard.
