Therefore, the only use of a Firewall on those machine is to block ads, stop prog that might send out sensitive info, control or stop program from accessing the internet rather than stop ppl attack you :) Quote : NAT very effectively HIDES all of your machines from the prying eyes of the Internet! Anyone scanning across your IP address will ONLY be able to "see" the NAT router! (Which is generally much more secure than the average PC.) So, they won't actually be touching any of your machines located BEHIND the router! Moreover, none of the software running inside your PC can "give out" your network's public IP address because it is completely unknown to your machines! Only the NAT router knows the public IP of your network, your machines only know their private "behind the router" IP's. So Internet client programs, like your web browser which send out the machine's IP address with every request, will be completely fooled and foiled when they're running behind a NAT router.
