Exploring IPTables and NetFilter: Advanced Packet Filtering in Linux

The IPTables/NetFilter application is considered to be the fourth generation of Linux packet filtering implementations. The first generation was Alan Cox's port of BSD UNIX's ipfw to Linux 1.1.

The first generation was Alan Cox's port of BSD UNIX's ipfw to Linux 1.1. Jos Vos and others extended this and added the ipfwadm user tool for manipulating the rules for filtering in the Linux 2.0 kernel. Paul "Rusty" Russell and Michael Neuling made some significant modifications to the 2.2 Linux kernel, and Russell added the user tool ipchains for controlling filtering rules for this kernel. Russell has now implemented a kernel framework called NetFilter. One of the goals of NetFilter was to provide a single, dedicated packet filter/mangler infrastructure that users and developers could deploy as an add-on built around the Linux kernel. For purposes of this article, packet filtering refers to the redirection of packets (but not modification of packet headers), while mangling refers to packet modification, typically of the source and/or destination IP address. NetFilter was designed to be modular and extensible. IPTables is a module that plugs into the NetFilter framework and allows the user access to kernel filtering/mangling rules and commands. If you are familiar with ipchains, you will notice the similarity between the syntax and format of IPTables and ipchains. The link for this article located at SysAdmin Magazine is no longer available. . Discover the power of Firewalld, the modern firewall management tool for Linux, boosting protection through dynamic rule sets..
