iptables and nftables are userspace utilities for interacting with the kernel side netfilter framework.I thought iptables was under nftables. I thought they worked together.
The netfilter project is a community-driven collaborative FOSS project that provides packet filtering software for the Linux 2.4.x and later kernel series. The netfilter project is commonly associated with iptables and its successor nftables.

iptables is a generic firewalling software that allows you to define rulesets. Each rule within an IP table consists of a number of classifiers (iptables matches) and one connected action (iptables target).
nftables is the successor of iptables, it allows for much more flexible, scalable and performance packet classification. This is where all the fancy new features are developed.
You will find many tutorials and documents, the nftables HOWTO documentation page is a good start. But since you are here, take a look at the Howto: Set up a basic nftables firewall that @Hallvor provided us.I need to follow this guideline: https://wiki.debian.org/nftables
