Hi Raj,

Try this. "route add -net 0.0.0.0 netmask 0.0.0.0 gw Your-host-Default-Gateway-IP". I got the same problem on the RHEL54 host on VMware guest OS, and it works after adding this new route.

And check with "route -n" and you should see new entry for the above.
From there you can ping to other network from your host or you can ssh to this RHEL host from other systems.

I hope this help for you.

P.S. This new route is for the Ethernet interface (eth0 mostly) which is connected to your Default-Gateway.
