# DigitalOcean Droplet Firewall Script
#===============================================================================
# This Firewall script is supposed to be used with DigitalOcean Droplets. It
# uses eth0 as external, and eth1 (if present) as internal network interface.
# It automatically detects IP addresses and blocks all traffic but SSH from a
# list of safe IP addresses.
# Two white lists can be defined, one for internal IPv4 IP addresses and one
# for public IPv4 addresses.
