A firewall router is a hardware device used to protect a network from unauthorized access. It serves as a barrier between the networked computers and other networks or the Internet. Firewall routers monitor the incoming and outgoing traffic going through the network and apply rules to either allow or block certain types of traffic. Firewall routers can also provide additional features such as NAT (Network Address Translation), Virtual Private Network (VPN) tunnels, Quality of Service (QoS) settings and more.
