Configuring the Linux Firewall with nftables
Control inbound and outbound traffic on a Linux host using nftables and the friendly ufw front-end to secure your network services.
Why a Host Firewall?
A host firewall decides which packets are allowed in or out of a single machine. It is your last line of defense, protecting services even when the network perimeter is breached.
From iptables to nftables
Modern Linux uses nftables as the kernel packet-filtering framework, replacing the older iptables. It uses tables, chains, and rules but with a cleaner, unified syntax.
