Create Firewall Rules with IPTables

Overview

IPTables is an IP packet filter firewall used for the Linux kernel. The filters are organized in different Netfilter modules known as tables which contain chains of rules for how to treat and filter through network packets.

Create a set of firewall rules with IPTables in your favorite Linux distribution.

It is recommended you have a foundational knowledge of TCP/IP, navigate the Linux terminal, how to create and navigate through virtual machines, and basics of how a packet filtering firewall works.
