useful if you want to set your machine up as a router.  Usually to use
this option you would have two (or more) network interfaces (not just
ethernet but modems, etc also) and packets would come in on one interface
expecting to get to their destination.  The ip_forwarding makes you
machine forward packets between interfaces.  On a laptop this is not going
to be useful, unless you use your laptop as a router ;)

This is usually off as in theory hackers could use your machine to forward
packets into secure networks and also hide their tracks, etc.
