Summary

Here’s a summary of the website content:

Nftables is a modern firewall framework offering a unified tool for building stateless and stateful firewalls, including features like NAT, transparent proxies, QoS routing, and advanced packet manipulation. It distinguishes itself through a consistent syntax, transactional rule updates (eliminating user-space locking), and flexible rulesets with user-defined tables, configurable hooks, and multiple actions per rule. Nftables leverages flowtables for performance and supports scripting through JSON, offering greater control and adaptability compared to older firewall technologies like ipset and iproute2.
