    a firewall is a special category of router that protects one network (the “trusted” network, such as your lan) from another (the “untrusted” network, such as the internet), while allowing communication between the two. a firewall incorporates the functions of a nat (network address translation) router, while adding features for dealing with a hacker intrusion or attack, and for controlling the types of traffic that can flow between the two networks. unlike simple internet sharing nat routers, a firewall uses a process called stateful packet inspection to protect your network from attacks and intrusions. nat performs a very limited stateful inspection in that it considers whether the incoming packet is in response to an outgoing request, but true stateful packet inspection goes far beyond nat.
