That command is only run on the laptop and not the router.

I am able to ping to and from my router machine to my laptop, it's just
that when I run the iptables commands that the router machine is no longer
able to access the net itself.
If I then do a /etc/init.d/networking restart, the router machine is able
to connect to the internet but the laptop is cut off.
thanks,
Sharukh.
