Please note ( as I mentioned in my previous mail) that  the 
only reason using the linux box with 2 lan is eth0 is used
to
dial up the 24online isp and then eth1 is used to redirect
the connection 
into the wan port of the router.
the utility of this router, it is a load balancing router
with 2 wan port.
one wan port is connected with data one BSNL connection
and the other port I am trying to connect with 24online
hence 
I'll get a load balancing setup. but I can't take out the
24online from the linux box due to configuration problem :-(
