NFTables, The Next Generation of Packet Classification Framework

iptables vs nftables

Over the years, XTables (IPTables, IP6Tables, ARPTables and EBTables) were using as user-space utility programs for packet filtering in Linux distributions such as Red Hat Enterprise Linux or Ubuntu. Now, Linux vendors are replacing XTables with next generation packet classification framework which called NFTables.

nftables replaces the popular {ip,ip6,arp,eb}tables. This software provides a new in-kernel packet classification framework that is based on a network-specific Virtual Machine (VM) and a new nft user-space command line tool. nftables reuses the existing Netfilter subsystems such as the existing hook infrastructure, the connection tracking system, NAT, user-space queuing and logging subsystem.
