nftables 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 queuing and logging subsystem.
Notes:
nftables is a subsystem of the Linux kernel that can protect against threats originating from within a corporate network to include malicious mobile code and poorly configured software on a host.
Run the following command to verify that nftables is installed:
dpkg-query -s nftables | grep 'Status: install ok installed'
Status: install ok installed
Run the following command to install nftables:
apt install nftables
None
