A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It establishes a barrier between a trusted internal network and untrusted external networks, such as the Internet. Firewalls have become essential for protecting computer networks from unauthorized access, malicious software, and other security threats.
Understanding how to avoid firewall restrictions can be crucial in various situations. For instance, if you’re a system administrator responsible for maintaining a secure network infrastructure, knowing how to configure firewall rules effectively is paramount. Additionally, if you’re a network user who frequently encounters firewall blocks while accessing certain websites or applications, learning techniques to bypass these restrictions can be beneficial.
