nftables
The current Linux packet filtering framework, which replaces iptables with tables, chains and rules managed by the nft command.
In more detail
A table of family inet covers IPv4 and IPv6 at once. firewalld and ufw write nftables rules underneath, and iptables commands are translated into it on current distributions.
