what are firewall routers?


Home firewall routers use network address conversion (NAT) to provide a single IP address from the Internet service between various home computers. When traffic from the Internet reaches your router, your router doesn't know which computer to send it to, so it throws the truck away. In effect, NAT acts as a firewall that prevents incoming requests from reaching your computer. Depending on your router, you may be able to block certain types of outgoing traffic by changing your router settings.
It is possible to forward some traffic to the router by setting up port forwarding or placing a computer in DMZ (demilitarized zone), where all incoming traffic is sent and activated. DMZ, of course, forwards all traffic to a particular computer: the computer will no longer benefit from the router, which acts as a firewall.
