Explanation & Hint:
- iptables: As mentioned earlier, iptables is a widely used firewall tool in Linux systems. It directly interacts with the packet filtering hooks in the Linux kernel, allowing you to set up rules that dictate the handling of inbound and outbound traffic. These rules can be used for various purposes such as blocking certain types of traffic, redirecting packets, logging them, and more. iptables is a command-line tool that provides a robust set of features for network filtering.
- gufw: This is a graphical user interface that simplifies the management of ufw (Uncomplicated Firewall), which is a front-end for iptables designed to simplify the process of configuring a firewall. While gufw itself does not directly set firewall rules at the kernel level, it provides an easy-to-use interface for creating and managing ufw rules, which are then translated into iptables rules.
