A Firewall Appliance is typically a black box piece of networking hardware and software system that is to function as the implementor of the defined access control policy. A fully featured firewall appliance will include NAT (Network Address Translation), DMZ (De-Militarized Zone), VPN (Virtual Private Network), Intrusion Detection and extensive audit logging with alarm condition detection and reporting. Content Filtering can be a highly desirable option to prevent pornography and specific non-work related web sites from being accessed.
