 Dual stack capable iptables firewall script
 
 ```
+supports two interfaces/addresses plus NAT support for VPN servers
+
+Terminology used in the script:
+"Public" an address where services are available
+"Private" (optional) another address where services are available
+
+Example:
 public and private are both public facing interfaces
 but have different ports allowed.  e.g. private (1.1.1.2)
 IP allows SSH and VPN access while public (1.1.1.1) allows
 HTTP.
