What is a Router Firewall?
A firewall monitors and controls incoming/outgoing traffic based on rules, blocking hackers, malware, and unauthorized access. Most modern routers like Netgear, TP-Link, Linksys have built-in firewalls enabled by default, but configuring them enhances security for US/UK home networks.

Steps for basic activation; advanced options vary.
- Access Admin: Enter 192.168.1.1, login.
