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.
Firewalls are configured (in hardware, software, or both) with specific criteria to block or prevent unauthorized access to a network. They work as filters for your network traffic by blocking incoming packets of information that are seen as unsafe.irewalls can be configured to filter by several variables: IP address, domain name, protocol, port or even specific words or phrases.
