Simple Anti DDOS Bash Script
This scrip provide basic protection for server unix/linux server or devices.

Let me demonstrate a basic protection usage:

Only port 80, 443 are allowed by default to your server, 
this allows web traffic to reach your server on both port 80(http) or 443(https)

Management port 2200 is whitelisted and allowed connection to the server, for managing purpose.

any ping from outsite the world.
