Netfilter is a free software community-driven project, launched in 1998, that provides the popular iptables firewalling tool for the GNU/Linux operating system. Starting Linux kernel 3.13, it also provides nftables, a new packet classification engine written from scratch that aims to resolve the existing design limitations of iptables, while retaining backward compatibility.

Projects

• High level library for nftables Lets develop a high level library for nftables that anyone can use, so nftables get the definitive bump to mainstream.
• Implement ebtables compatibility layer nftables framework provides compatibility layers for existing {ip, ip6, arp} firewall tools. ebtables compatibility layer is missing yet, and the goal of this task is to implement it.
• Task 1: Automatic translation from iptables to nftable To ease the migration from iptables to nftables, we have to provide a translation software that will convert the old iptables rule-sets to the new nftables syntax.
