How to configure RADIUS on 2 IP address Server

[Pongsak Tawankanjanachot]

Hi,
   I'm setting up RADIUS server to use with Wireless network
  1) RADIUS server is Debian (eth0=192.168.25.254 (support all local
computer, Access point) and eth1=192.168.2.45 (to Internet)
  2) Access Point is LinkSys WAP54G (192.168.25.75)
  3) Client is Dell Inspiron with Intel Broadcom wireless network card.

   My setting RADIUS server has 2 network cards. They are
   I started installing, ,setting, running ./radiusd -X with default
configuration.
   Everything seems find. Server is running.
==================================================================
  On Server terminal, I test with radtest test test localhost 0 testing123
  Debug message shows up:

Sending Access-Request of id 102 to 127.0.0.1 port 1812
        User-Name = "test"
        User-Password = "test"
        NAS-IP-Address = 127.0.1.1
        NAS-Port = 0
rad_recv: Access-Request packet from host *192.168.2.45 *port 36272, id=102,
length=56
        User-Name = "test"
        User-Password = "test"
        NAS-IP-Address = 127.0.1.1
        NAS-Port = 0

then it ends with

Sending Access-Accept of id 102 to* 192.168.2.45* port 36272
        Framed-MTU = 1400
        NAS-IP-Address = 192.168.25.77
        NAS-Port = 15
Finished request 5.
Going to the next request
Waking up in 4.9 seconds.
rad_recv: Access-Accept packet from host 192.168.2.45 port 1812, id=102,
length=38
radclient: received response to request we did not send. (id=102 socket 3)
Sending Access-Request of id 102 to 127.0.0.1 port 1812
        User-Name = "test"
        User-Password = "test"
        NAS-IP-Address = 127.0.1.1
        NAS-Port = 0

My question is why the Access-Accept is to 192.168.2.45 (It should be
192.168.25.254??)
I also try to use RTRadPing Test Utility from local computer-WinXP SP3 (
192.168.25.142) asking Authentication Request to 192.168.25.254
RTRadPing says no response from server, timeout.

Seems like my ./radiusd runs on *192.168.2.45* ?? (eth1)

==================================================================
  On Server terminal, I try again with  radtest test test 192.168.25.254 0
testing123

Sending Access-Request of id 162 to 192.168.25.254 port 1812
        User-Name = "test"
        User-Password = "test"
        NAS-IP-Address = 127.0.1.1
        NAS-Port = 0
rad_recv: Access-Request packet from host 192.168.25.254 port 36275, id=162,
length=56
        User-Name = "test"
        User-Password = "test"
        NAS-IP-Address = 127.0.1.1
        NAS-Port = 0

then it ends with

Sending Access-Accept of id 162 to 192.168.25.254 port 36275
        Framed-MTU = 1400
        NAS-IP-Address = 192.168.25.77
        NAS-Port = 15
Finished request 6.
Going to the next request
Waking up in 4.9 seconds.
rad_recv: Access-Accept packet from host 192.168.25.254 port 1812, id=162,
length=38
        Framed-MTU = 1400
        NAS-IP-Address = 192.168.25.77
        NAS-Port = 15

==================================================================
Then, I kill ./radiusd
start with ./radiusd -i 192.168.25.254 -p 1812 -X &  (I start it in
background mode, fix IP+Port)
It ends with...
radiusd: #### Opening IP addresses and Ports ####
Listening on authentication address 192.168.25.254 port 1812
Listening on accounting address 192.168.25.254 port 1813
Listening on proxy address 192.168.25.254 port 1814
Ready to process requests.

Seems like RADIUS is listening on 192.168.25.254..... :D

==================================================================
  On Server terminal, I test with radtest test test localhost 0 testing123

Sending Access-Request of id 103 to 127.0.0.1 port 1812
        User-Name = "test"
        User-Password = "test"
        NAS-IP-Address = 127.0.1.1
        NAS-Port = 0

*There is no response at all....*

if I try with radtest test test 192.168.25.254 0 testing123
It ends with

Sending Access-Accept of id 88 to 192.168.25.254 port 36277
        Framed-MTU = 1400
        NAS-IP-Address = 192.168.25.77
        NAS-Port = 15
Finished request 1.
Going to the next request
Waking up in 4.9 seconds.
rad_recv: Access-Accept packet from host 192.168.25.254 port 1812, id=88,
length=38
        Framed-MTU = 1400
        NAS-IP-Address = 192.168.25.77
        NAS-Port = 15

 It replies!! Seems like it is listening at eth0 192.168.25.254 port 1812
BUT when I use RTRadPing Test Utility from local computer-WinXP SP3 (
192.168.25.142) asking Authentication Request to 192.168.25.254
RTRadPing says no response from server, timeout.

What should I do next??
Somebody can suggest me?
I think this is just the first step, then I need to install OpenSSL and
test....a long way to go..


Best regards,
