[Dhirendra Pal Singh <list@xxxxxxxxxxxxxx>]

Hi All,
I have the following setup on redhat linux 8.0 ...

                                                                eth 0 
192.168.1.50
                                                                   \
                    |--------------|                              \ 
|--------------|
-----------------| gateway 1|-------------------------|gateway2  |
                   /|_______   |\                               
|--------------|
                 /                      \                             / 
                 \
           eth0                   eth1 -                       /        
               \
       61.X.X.X          192.168.1.1              eth1                
   eth2
     (public)                         |                192.168.2.51     
   192.168.3.52
                                           |                          
                           |
                                   ------------                       
                       |
                                   |  BOX 1   |                         
        ----------------                                  
                                   -------------                     
             |   Box 3      |
                                192.168.1.101                          
      ---------------
                                                                      
               192.168.3.101

My Problem is

A) I am unable to ping from Box 3 (192.168.3.101) to Box 1. Any comments 
or reasons why?
B) I have figured out that if I enable Masquerading then problem A is 
solved. Can someone explain why?
C) Is it possible without Masquerading ?

I am in a fix and any Help would be very much appreciated...??

Thanks and Regards
