About:
nftables is the user-space command-line tool used to configure the Linux kernel's inbuilt packet filtering framework, also named nftables. It provides a simplified syntax and more efficient processing compared to its predecessor, iptables. This tool is essential for managing network traffic rules, firewalls, and network address translation (NAT) on modern Linux systems.
Key Features:
  • Unified syntax replacing ip(6)tables, ebtables, and arptables
  • Improved performance with a single packet processing pipeline
  • In-kernel packet filtering and NAT capabilities
  • Compatibility layer for legacy iptables syntax
Use Cases:
  • Configuring host-based firewalls on Linux servers
  • Implementing Network Address Translation (NAT) for routing
  • Filtering network traffic based on IP, port, and protocol
Alternatives:
  • iptables – The legacy utility for packet filtering; nftables offers a more efficient and flexible architecture.
  • ufw – A user-friendly interface for managing firewalls that often uses nftables or iptables as a backend.
