Firewall Purpose and Role

The primary purpose of a firewall is to act as a barrier between a trusted network and an untrusted network, such as the internet.
The role of a firewall in network security is to control incoming and outgoing network traffic based on predetermined security rules.

Firewall rules are used to determine what traffic is allowed or blocked, and are typically based on source and destination IP addresses, ports, and protocols.
