Nftables

nftables is a subsystem of the Linux kernel providing filtering and classification of network packets/datagrams/frames. It has been available since Linux kernel 3.13 released on 19 January 2014. nftables replaces the legacy iptables portions of Netfilter. Among the advantages of nftables over iptables is less code duplication and easier extension to new protocols. nftables is configured via the user-space utility nft, while legacy tools are configured via the utilities iptables, ip6tables, arptables and ebtables frameworks.
