This enables additional modifications by rules that follow, such as NAT or further filtering. iptable_mangle module Registers a hook and mangle table to run after Connection Tracking (see below) (but still before any other table), so that modifications can be made to the packet. It provides a table called raw that can be used to filter packets before they reach more memory-demanding operations such as Connection Tracking. Iptable_raw module When loaded, registers a hook that will be called before any other Netfilter hook.

Netfilter modules not organized into tables (see below) are capable of checking for the origin to select their mode of operation. Locally generated output passes through the OUTPUT chain, and packets to be sent out are in POSTROUTING chain. Packet reception, for example, falls into PREROUTING, while the INPUT represents locally delivered data, and forwarded traffic falls into the FORWARD chain. These chain titles help describe the origin in the Netfilter stack. These chains are named with predefined titles, including INPUT, OUTPUT and FORWARD. Rules are organized into chains, or in other words, 'chains of rules'. Any table can call itself and it also can execute its own rules, which enables possibilities for additional processing and iteration. As far as Netfilter is concerned, it runs a particular table in a specific order with respect to other tables. Notice that although both the kernel modules and userspace utilities have similar names, each of them is a different entity with different functionality.Д®ach table is actually its own hook, and each table was introduced to serve a specific purpose. The tables can be administered through the user-space tools iptables, ip6tables, arptables, and ebtables. They provide a table-based system for defining firewall rules that can filter or transform packets. The kernel modules named ip_tables, ip6_tables, arp_tables (the underscore is part of the name), and ebtables comprise the legacy packet filtering portion of the Netfilter hook system.

In 2017 IPv4 and IPv6 flow offload infrastructure was added, allowing a speedup of software flow table forwarding and hardware offload support. The connection tracking and NAT subsystems are more general and more powerful than the rudimentary versions within ipchains and ipfwadm. Each connects to the Netfilter hooks at different points to access packets. Whereas ipchains and ipfwadm combine packet filtering and NAT (particularly three specific kinds of NAT, called masquerading, port forwarding, and redirection), Netfilter separates packet operations into multiple parts, described below.

Both ipchains and ipfwadm alter the networking code so they can manipulate packets, as Linux kernel lacked a general packets control framework until the introduction of Netfilter. Prior to iptables, the predominant software packages for creating Linux firewalls were ipchains in Linux kernel 2.2.x and ipfwadm in Linux kernel 2.0.x, which in turn was based on BSD's ipfw. In September 2007 Patrick McHardy, who led development for past years, was elected as new chairman of the coreteam. In April 2004, following a crack-down by the project on those distributing the project's software embedded in routers without complying with the GPL, a German court granted Welte an historic injunction against Sitecom Germany, which refused to follow the GPL's terms (see GPL-related disputes). In August 2003 Harald Welte became chairman of the coreteam. The software they produced (called netfilter hereafter) uses the GNU General Public License (GPL) license, and in March 2000 it was merged into version 2.4.x of the Linux kernel mainline. As the project grew, he founded the Netfilter Core Team (or simply coreteam) in 1999. Rusty Russell started the netfilter/iptables project in 1998 he had also authored the project's predecessor, ipchains.
