firewallsetup

Fast Firewall Setup

This is a script for setting up a firewall with settings for tarpitting ssh and basic protections that everyone needs.

Download the rules to /etc/

git clone https://github.com/ChrisTitusTech/firewallsetup.git

Make the Rules Permenant

Debian-based Distributions

sudo apt install iptables-persistent
sudo /etc/init.d/netfilter-persistent save

Arch Linux Distributions

Use iptable-save which is pre-installed

sudo iptables-save > /etc/iptables/iptables.rules

RHEL / CentOS Distributions

This is by far the simpliest way to save rules and check them # chkconfig --list | grep iptables

Note: chkconfig iptables on only needs to be run once to turn the service on

sudo chkconfig iptables on
sudo service iptables save
