For this documentation I will use this bogus IP address to represent the address assigned to the droplet: 123.456.789.012. Yes, I am aware of the irony that I am not documenting the actual IP address, then tell how to find it in a few paragraphs.</p> http://localhost:1313/posts/linux_ufw/ Sun, 01 Feb 2026 00:00:00 +0000 http://localhost:1313/posts/linux_ufw/ <p>The Linux kernel includes the <strong>Netfilter</strong> subsystem, which is used to manipulate or decide the fate of network traffic headed into or through your server. All modern Linux firewall solutions use this system for packet filtering.</p> <p>The kernel’s packet filtering system would be of little use to administrators without a userspace interface to manage it. This is the purpose of the <code>**iptables**</code> utility: when a packet reaches your server, it will be handed off to the Netfilter subsystem for acceptance, manipulation, or rejection based on the rules supplied to it from the userspace (via <code>iptables</code>). Thus, <code>iptables</code> is all you need to manage your firewall, if you’re familiar with it, but many are available to simplify the task. We’ll take a look at the default frontend used in Ubuntu here.</p>
