Neuron P2P Diagnostics v1.0.3 - Windows Firewall Rules Checking

🔧 Update v1.0.3 - Windows Firewall Rules Checking

🆕 New Feature: Windows Firewall Rules Analysis

• ✅ Windows Firewall Integration: Added comprehensive Windows Firewall rules checking
• ✅ Service Status Check: Verifies Windows Firewall service is running
• ✅ Inbound/Outbound Rules: Queries both inbound and outbound firewall rules
• ✅ Port-Specific Analysis: Finds rules that specifically affect your P2P port
• ✅ Port Range Support: Detects rules for port ranges (e.g., 61336-61346)
• ✅ Protocol Filtering: Focuses on TCP/UDP rules relevant to P2P
• ✅ Detailed Reporting: Shows specific blocking/allowing rules found

How It Works

The tool now queries Windows Firewall using netsh commands to:

1. Check Service Status: Verifies Windows Firewall service is active
2. Query Inbound Rules: Finds rules affecting incoming connections
3. Query Outbound Rules: Finds rules affecting outgoing connections
4. Parse Rule Details: Extracts rule names, actions (Allow/Block), and ports
5. Port Matching: Identifies rules that affect your specific P2P port
6. Generate Report: Provides actionable information about firewall blocking

Example Output

Windows (with firewall rules):

⚠️ Windows Firewall Rules: WARNING
   Firewall rules may block this port
   Details: Inbound blocking: 1 rules | Outbound blocking: 0 rules | Inbound allowing: 0 rules | Outbound allowing: 2 rules | Blocking inbound rules: - Block P2P Ports (Block)

Non-Windows (skipped):

✅ Windows Firewall Rules: SKIP
   Windows Firewall check not applicable
   Details: This test only runs on Windows systems

Benefits

• 🎯 Accurate Diagnostics: Distinguishes firewall blocking from other issues
• 🔍 Actionable Information: Shows exactly which rules are blocking ports
• 🛡️ Security Awareness: Helps users understand their firewall configuration
• 📊 Comprehensive Analysis: Works alongside existing firewall analysis
• 💻 Windows-Specific: Provides detailed Windows Firewall information

Downloads

• Windows: network-diagnostics-windows.exe (3.4 MB) - Now with Windows Firewall checking!
• macOS: network-diagnostics-macos (3.2 MB)
• Linux: network-diagnostics-linux (3.2 MB)

Usage

# Test specific port with Windows Firewall analysis
./network-diagnostics 61340

# Windows: Double-click the .exe file
# The window will stay open until you press Enter

Technical Details

• Uses netsh advfirewall firewall show rule commands
• Parses rule output to extract port, protocol, and action information
• Supports port ranges and protocol filtering (TCP/UDP/Any)
• Only enabled on Windows systems for optimal performance
• Integrates seamlessly with existing diagnostic suite

This update provides Windows users with detailed firewall analysis to help troubleshoot P2P connectivity issues!

Neuron P2P Diagnostics v1.0.2 - Fixed NAT Detection

🔧 Update v1.0.2 - Fixed NAT Detection

🐛 Bug Fix

• ✅ Fixed NAT Detection: Resolved critical issue where NAT test always reported 'No NAT'
• ✅ Proper Local IP Detection: Now correctly detects private IP addresses (192.168.x.x, 10.x.x.x, etc.)
• ✅ Accurate NAT Classification: Properly identifies NAT types (Restricted Cone, Port Mapping, etc.)
• ✅ Port Mapping Detection: Now correctly detects when local port != public port

What Was Fixed

The NAT detection was failing because was nil, causing the logic to incorrectly assume a public IP. Now:

• Properly retrieves local IP from UDP connection
• Correctly identifies private IP ranges
• Shows accurate NAT type and port mapping status

Example Output (Before vs After)

Before (Broken):

After (Fixed):

Downloads

• Windows: network-diagnostics-windows.exe (3.4 MB) - Double-clickable with pause
• macOS: network-diagnostics-macos (3.2 MB)
• Linux: network-diagnostics-linux (3.2 MB)

Features

• 🎯 Specific port testing with command line arguments
• 🔍 Fixed STUN-based NAT type detection with accurate port mapping analysis
• 🛡️ Comprehensive firewall blocking detection
• 🌐 Real UDP connectivity testing with echo verification
• 📊 P2P port range communication testing (61336-61346)
• 💻 Cross-platform support (Windows, macOS, Linux)

Usage

# Test specific port
./network-diagnostics 61340

# Windows: Double-click the .exe file
# The window will stay open until you press Enter

This update ensures accurate network diagnostics for P2P applications!

Neuron P2P Diagnostics v1.0.1 - Windows Double-Click Support

🔧 Update v1.0.1 - Windows Double-Click Support
