Version License Platform

WPF GUI suite for Windows Firewall rule management. Two tools: a live manager for your system firewall and an offline editor for safe rule manipulation on backup files.

Tools

FirewallManager.ps1

Live firewall rule management:

  • Browse all rules in a searchable DataGrid with Group column
  • Inline editing (enabled, action, profile, protocol, ports)
  • Backup rules to .fwbackup files (netsh export wrapped in JSON with metadata)
  • Restore from backup
  • Delete rules (multi-select)
  • Export to CSV
  • Filter by name, program, port, description
  • Filter by Group via dropdown
  • Find Duplicates - scans rules for matching program + direction + action + ports, shows report and filters grid
  • Quick Block menu - one-click blocking for programs (file browser), ports (text input), or IP addresses (text input)
  • Collapsible Stats Panel - total/inbound/outbound, enabled/disabled, allow/block, by profile counts
  • Search Highlighting - bold + colored rows when search filter is active

FirewallRulesEditor.ps1

Offline backup editor:

  • Import .fwbackup files created by FirewallManager
  • Browse, edit, and delete rules without touching your live firewall
  • Export modified rulesets back to .fwbackup or CSV
  • Merge Import - import a second backup and merge new rules into the current set (deduplicates by name)
  • Show Changes - diff view comparing current state to the original import (added, deleted, modified rules)
  • Rule count in title bar - always shows current rule count
  • Safe sandbox for planning firewall changes

Usage

# Live firewall management (requires Administrator)
.\FirewallManager.ps1

# Offline backup editing (no admin needed)

Requirements

  • Windows 10/11
  • PowerShell 5.1+
