The internet is a vast and exciting place, but sometimes, your firewall can act as a gatekeeper, blocking access to websites and applications you need or want to use. This can be frustrating, especially when you’re trying to work, stream your favorite shows, or connect with friends and family online.
But fear not! Understanding how firewalls work and how to configure them can help you regain control over your internet access. This guide will equip you with the knowledge and steps to unblock your internet firewall effectively.
Understanding Firewalls and Their Purpose
A firewall is a security measure that acts as a barrier between your computer and the internet. It’s designed to protect your device from unauthorized access, malware, and other online threats.
