Adoption

This page offers some light and data about current nftables adoption in the wider community. As you probably know, the focus of the Netfilter project and community is in replacing the iptables framework with nftables, adding brand new features and refreshing some workflows along the way.

Lots of upstream projects use iptables to handle NAT, filtering, mangling or other networking stuff. Here, the info we know about them, their relationship with nftables and the possibilities for them to migrate to nftables.

Cases

Known cases and examples we could heard of. TODO: extend with more current data.

All major Linux distributions contains the nftables framework ready to use. Check Nftables from distributions.

system / firewalling / management

Supporting nftables

The following projects are known to either directly support nftables or have authors actively working on nftables integration.

• https://www.fail2ban.org/ -- the fail2ban tool already includes native support for nftables.
• https://firewalld.org/ -- firewalld by RedHat is currently developing a native integration with nftables.
• https://suricata-ids.org/ -- suricata can work natively with nftables (link)
• https://keepalived.org/ -- keepalived works natively with nftables ([1])

Supporting iptables only

The following projects are known to only support iptables/iptables-nft, with no plans to support nftables in the future.

virtualization / cloud / infrastructure

• https://github.com/zevenet/nftlb -- nftlb by Zevenet is a nftables-based loadbalancer which can outperform LVS by 10x
• https://www.docker.com/ -- Some discussion happened in the Docker community regarding a native integration with nftables, which could ease some of their use cases (link) (link) (running docker with IPv6 using nftables)
• https://kubernetes.io/ -- Kubernetes does not support nftables yes, but some discussion happened already (link). Compat tools may be used to trick kubernetes into using nftables transparently.
• http://openstack.org/ -- Openstack does not support nftables yet. Compat tools may be used to trick neutron and other components into using nftables transparently.
• https://libvirt.org/ -- there are reports of people running libvirt with nftables for bridge filtering for virtual machines
• https://saltstack.com/ -- SaltStack includes native support for nftables (link).
• https://coreos.com/ -- the CoreOS ecosystem includes native support for nftables (link)
