About Shorewall

Shorewall was created in 2001 to simplify the configuration of Netfilter, the packet filtering framework within the Linux kernel. It provided a more user-friendly way to manage firewall rules and policies through a set of configuration files, addressing the complexity and manual effort required by direct Netfilter management.

Strengths of Shorewall include its user-friendly configuration, flexibility, and powerful rule management capabilities. Weaknesses involve a steep learning curve for beginners and less frequent updates. Competitors include iptables, UFW (Uncomplicated Firewall), and Firewalld.
