Learn how to secure an Ubuntu server with UFW (Uncomplicated Firewall) in this complete, hands-on Linux firewall tutorial. We’ll install UFW, configure secure default policies, create firewall rules, protect SSH, allow Apache traffic, limit connections, manage subnets and port ranges, enable logging, and explore the GUFW graphical interface.
Whether you’re a Linux beginner, system administrator, homelab enthusiast, or server administrator, this practical guide will help you understand how UFW works and how to use it safely. You’ll also learn the difference between deny and reject, how to check active rules, and how rate limiting can help protect SSH against brute-force attacks.
