<P>&nbsp;</P>
<P>Machine 1 and Machine&nbsp;3 are on different subnet. </P>
<DIV></DIV>
<DIV></DIV>from Machine 1 and&nbsp;3 &nbsp;I can ping both interfaces of&nbsp; Machine 2 Linux Boxes. But I am unable to Ping Machine&nbsp;3 from Machine 1 and vice versa. I have tried to make my Machine 2 Linux Box as Router, I have made static entries in the kernel routing table as well. But still problem persists. I am not sure if I am missing anything in the configuration of Linux Box as a router. 
<DIV></DIV>
<DIV></DIV>Can&nbsp;anyone &nbsp;please&nbsp;tell me where I am making mistake. 
<DIV></DIV>
<DIV></DIV>Thanks
