Getting a Router can be a big help too. They can't attack your machine
if they can't see the IP address. With a Router they see the router's
address and not your PC's.

A router can help, to be sure. But all that does is add an extra layer for
an attacker to get through. Routers can be hacked too (though, since they
are simpler devices, it's harder to do).

Even a hardware firewall isn't perfect.
