## About ##
iptablesbuild is a configuration management engine for iptables. The goal is to have one configuration file to manage an entire network of systems.

In large networks, individual host firewall configurations tend to share a large number of similarities with eachother. This can be access to email servers, file servers, etc. The general idea with iptablesbuild is to create a generic global configuration that all systems use, and have custom deviations for each individual configuration. This can turn a very complicted long configuration into a very simple one.

What does this accomplish?:
 1. Standardization for how the iptables configurations are organized and what rules are in place. This allows for better readability, and ensures that certain protections are always in place.
 2. Reduced duplication of unneeded rules. Often in large installations iptables configurations are copied from one system to annother without looking through to see what is needed and what isn't. iptablesbuild won't eliminate this, but it will reduce the amount of imformation a sysadmin needs to look through.
 3. Reduces user error. When the same base configuration is used on multiple systems with the same ordering scheme, it is less likely for a problem to occur where a rule in in the wrong place causing the rule to not have any effect or loss of access.
