Proxy firewall. An early type of firewall device, a proxy firewall serves as the gateway from one network to another for a specific application. Proxy servers can provide additional functionality such as content caching and security by preventing direct connections from outside the network.
A Firewall is an entity (a device or a group of devices) designed to control (permit or deny) network traffic using a set of rules. A Firewall is designed to permit only the authorized communications to pass through it. A Firewall can be implemented in both hardware and software. Software-based firewalls are a common place in many personal computer operating systems. Moreover, firewall components are contained in many routers. Conversely, many firewalls can perform functionality of routers as well.
