# This script is a basic IPTables server firewall with defenses against some
# of the most common attack types.
#
# Basically you just have to add/remove ports in the first part of this script
# and you should be ready to go.
# 
# Help, comments and improvements always appreciated, also, feel free to
# use, change and distribute. Cheers
