What is nftables

https://netfilter.org/projects/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 userspace command line tool. nftables reuses the existing Netfilter subsystems such as the existing hook infrastructure, the connection tracking system, NAT, userspace queueing and logging subsystem.

Nftables/Examples

https://wiki.gentoo.org/wiki/Nftables/Examples
On this page several example nftable configurations can be found. The first two examples are skeletons to illustrate how nftables works. The third and fourth exmaple show how, using nftables, rules can be simplified by combining IPv4 and IPv6 in the generic IP table 'inet'. The fifth example shows how nftables can be combined with bash scripting.
