It can either be used as a loadable kernel module or incorporated into your UNIX kernel; use as a loadable kernel module where possible is highly recommended. Scripts are provided to install and patch system files, as required. IP Filter is distributed with FreeBSD, NetBSD, and Solaris. OpenBSD users should see Openbsd PF and Linux users Netfilter.

It handles network address translation, normalizing TCP/IP traffic, providing bandwidth control, and packet prioritization. It also offers some eccentric features, such as passive OS detection. Coming from the same guys who created OpenBSD, you can trust that it has been well audited and coded to avoid the sort of security holes we have seen in other packet filters.

The userspace iptables tool is used for configuration. It now supports packet filtering (stateless or stateful), all kinds of network address and port translation (NAT/NAPT), and multiple API layers for 3rd party extensions. It includes many different modules for handling unruly protocols such as FTP. For other UNIX platforms, see Openbsd PF (OpenBSD specific), or IP Filter. Many personal firewalls are available for Windows (Tiny,Zone Alarm, Norton, Kerio, …), though none made this list. Microsoft included a very basic firewall in Windows XP SP2, and will nag you incessantly until you install it.
