freeradius not responding on machine specific IPs

Just to be "sure", iptables has been set to accept all.
A netstat shows:
> udp 0 0 *:radius *:*
> udp 0 0 *:radius-acct *:*
So radius appears to be "listening" to the ports on "ALL" IPs. If the
above is correct, then I should be able to do a radtest on any IPs
associated with the box and get a response. Yet I am only able to get a
response using localhost (127.0.0.1)...
Just to be sure, I also did a localhost radtest on the machine:
> radtest fred wilma localhost 1812 mysecret
And it resolved localhost as 127.0.0.1 (as expected) and responded the
same as when I used 127.0.0.1
In radiusd.conf, bind_address = * and listen { } is all commented out.
Running freeradius -XXX -A provides the following output:

Still confused as to why it won't respond to other IPs on the
server... :-(
