It's highly effective for setting up firewalls and manipulating how data packets are handled. This blog post will guide you through the basics of iptables, including how to install it across different Linux distributions and some fundamental rules for managing your firewall. iptables is a command-line firewall utility that uses policy chains to allow or block traffic.
