Shorewall

What is Shorewall?

The Shoreline Firewall, or "Shorewall," is a powerful and flexible firewall solution that enables users to configure complex network security policies with ease. Shorewall is a high-level tool that simplifies the configuration of Netfilter, the Linux kernel's built-in firewall framework. By using a set of intuitive configuration files, users can define their firewall and gateway requirements, and Shorewall will handle the underlying Netfilter and Linux networking subsystem configurations to implement those policies

Highlights

• Versatile Deployment: Shorewall can be used on dedicated firewall systems, multi-function gateways/routers/servers, or standalone GNU/Linux systems, providing users with the flexibility to tailor the solution to their unique network environments
• Advanced Netfilter Integration: Shorewall leverages Netfilter's connection state tracking capabilities, allowing for more sophisticated firewall rules and policies compared to older ipchains-based approaches
• Intuitive Configuration: Users can define their firewall and gateway requirements using a set of configuration files, enabling them to manage complex network security policies without delving into the intricacies of low-level iptables, ip, and tc commands.
