[Help-gnu-radius] ~radius - configure help~

Dear Sir,
                      
            We are doing a project titled "Integrating Mobile IP for
            Authentication, Authorization and Accounting over RADIUS". We
            are using the software "Dynamics - Mobile IP" developed at
            Helsinki University of Technology
            (http://dynamics.sourceforge.net). Since we have hardware
            limitations, we are implementing Mobile IP in a wired
            environment. 
          
             We have 4 computers running Red Hat Linux 7.3, connected
             through a 2 hubs 

Home agent     HA  -> 172.168.242.1 (eth0) & 172.168.240.5 (eth1)
Foreign Agent  FA  -> 172.168.240.1
Mobile Node    MN  -> 172.168.242.2 (initial setup ) -> 172.168.240.2
(final point of attachment) 
RADIUS             -> 172.168.242.5 

             Our initial setup is  
             HA (172.168.242.1 eth0) --hub1-- MN (172.168.242.2)
                                        |
                                     RADIUS 

             Final setup is
             RADIUS--hub1--HA(172.168.240.5
             eth1)--hub2--FA(172.168.240.1)-- MN (172.168.242.2) 
                      |
                      |
              HA (172.168.242.1 eth0)

              We are simulating the movement of mobile node from one
              network to another in a wired environment by changing the
              IP address of MN manually (without DHCP). Since we are new
              to the world of radius, we are facing difficulties in
              configuring radius to suit our environment.

We have the following problems:

We need radius to AAA the mobile node. 
1. We do not have a NAS. How do we make radius to work without a NAS?
2. How do we change configuration in radius to accept the mobile node and
validate it?
3. Do we need to install the radius program in the mobile node also in
order to run programs like radtest?
              
Thanks in advance.
