iptables formula
================

iptables is a user-space application program that allows a system administrator to configure the tables provided by the Linux kernel firewall and the chains and rules it stores.
Iptables is used to set up, maintain, and inspect the tables of IPv4 packet
filter rules in the Linux kernel. Several different tables may be defined.
Each table contains a number of built-in chains and may also contain
user-defined chains. Each chain is a list of rules which can match a set of
packets. Each rule specifies what to do with a packet that matches. This is
called a `target`, which may be a jump to a user-defined chain in the same
table.

Sample pillars
==============

Simple INPUT chain httpd ACCEPT rule on position 1
Most common rules - allow traffic on localhost, accept related,established and
ping
