My personalized version of a language that represents iptable rules.
What is Nate's Firewall? Nate's Firewall (or nfw) translates string representation of a rule to the needed parameter list for iptables.
For example this line:
nfw deny input 127.0.0.1 source
-A INPUT -s 127.0.0.1 -j DENY
This program's goal is to make it easier to maintain iptables firewalls without having to learn what dashes need to go where.
Added some help information - access it by typing nfw help
Added cstate rule
