radiusd server does not respond to radtest from another host

Something may be wacky with the network configuration on the 10.10.10.10
machine. The packet capture shows that the NAS-IP-Address attribute is set
to 127.0.0.2 but it should be 10.10.10.10. Since 127.0.0.2 is not in
clients.conf, the request will be ignored. Try running radtest with the
following options
radtest pencil richard6 10.10.10.11 0 testing123 1 10.10.10.10
If you still have a problem, send the following additional information .
1. The rest of the debug output from radiusd -X on the 10.10.10.11
machine. The output at the bottom of this message only shows that startup of
radiusd.
2. The output from radtest when you run it on 10.10.10.11.
3. The output from radtest when you run it on 10.10.10.10.

Subject: radiusd server does not respond to radtest from another host
Hi All,
I installed FreeRADIUS Version 2.1.1, for host i686-suse-linux-gnu on
OpenSuse 11.1 using Yast. I am having problems testing the radius server
10.10.10.11 from an external host 10.10.10.10 using radtest.
Background: I configured clients.conf, users and radiusd.conf. After
changing permissions on the /etc/radb/certs directory I was able to start
"radiusd -X" without any reported errors, warnings.
I then successfully tested locally using radtest in another terminal window
on the radius server (IP = 10.10.10.11)
linux-au5f:/home/michael # radtest pencil richard6 10.10.10.11 0 testing123
Sending Access-Request of id 63 to 10.10.10.11 port 1812
User-Name = "pencil"
User-Password = "richard6"
NAS-IP-Address = 127.0.0.2
NAS-Port = 0
rad_recv: Access-Accept packet from host 10.10.10.11 port 1812, id=63,
length=35
Reply-Message = "Hello, pencil"
Next I tried testing radiusd using radtest from a 2nd host (10.10.10.10),
which I had added previously added to the clients.conf (Note I can
successfully ping the radius server 10.10.10.11 from this 2nd host
10.10.10.10). But, I get no response from radius acc-request on either the
radiusd terminal window or the radtest terminal window.
Below is the clients.conf definitiion
client dellM65 {
ipaddr = 10.10.10.10
require_message_authenticator = no
secret = "testing123"
nastype = "other"
}
I did a capture with Wireshark and I can see the radius request, but no
responses. Have I missed some part of the Freeradius config to recognize the
external radtest host?
I have attached some output to hopefully answer anything not described
above.
Attached is the radiusd -X output
