Versions:
fwall 1.2.0 by Hashibutogarasu is a lightweight command-line utility designed to streamline Windows Defender Firewall management without requiring graphical interfaces or elevated scripting knowledge. Classified under System Utilities, the program exposes a concise set of verbs that let administrators list, create, modify, or delete inbound and outbound rules, toggle profiles, and monitor active firewall state from PowerShell or classic cmd sessions. Typical use cases include automating server lock-down during deployment pipelines, quickly opening transient ports for development servers, scripting baseline hardening for SOHO workstations, and integrating firewall changes into larger batch maintenance routines where GUI interruptions are impractical. Because all operations map directly to standard Windows APIs, changes enacted through fwall are immediately reflected in the native Windows Security Center and remain compatible with Group Policy, MDM, and third-party auditing tools. The tool’s fifth public release introduces rule-name pattern matching, export-to-CSV, and improved error codes, while still supporting earlier syntax for backward compatibility across versions 1.0 through 1.1.x. Portable single-executable distribution keeps the utility below 200 KB, so it can be carried on a thumb drive or pushed through remote execution frameworks without installation. No additional runtimes or drivers are required on Windows 8, 10, 11, and equivalent Server editions. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
