firewalls are commonly used in conjunction with routers that connect an intranet to the internet. In this setup, the firewall provides an additional layer of security by controlling and monitoring the flow of traffic between the internal network (intranet) and the external network (internet). The combination of a router and a firewall is often referred to as a "firewall router" or "gateway router."
