apf - easy iptables based firewall system
This manual page documents briefly the apf command. This manual page was written for the
Debian distribution because the original program does not have a manual page.
Advanced Policy Firewall (APF) is an iptables (netfilter) based firewall system designed
around the essential needs of today's Internet deployed servers and the unique needs of
custom deployed Linux installations. The configuration of APF is designed to be very
informative and present the user with an easy to follow process, from top to bottom of the
configuration file. The management of APF on a day-to-day basis is conducted from the
command line with the 'apf' command, which includes detailed usage information and all the
features one would expect from a current and forward thinking firewall solution.
apf follow the usual GNU command line syntax, with long options starting with two dashes
(`-'). A summary of options is included below.
