In this video, we'll set up UFW (Uncomplicated Firewall) on Ubuntu 24.04 from scratch. UFW sits on top of iptables and lets you write firewall rules in plain English without no cryptic syntax, no afternoon-long config sessions. We'll cover: What a firewall actually does (and why you need one) The one mistake that will lock you out of your own server How to allow, deny, and rate-limit traffic Managing and auditing your rules over time ⚠️ Before you do anything else: allow SSH before you enable UFW. I cannot stress this enough.
