Check Outbound Ports

A PowerShell script to test outbound TCP connectivity from your Windows machine. This script dynamically prompts the user to validate outbound communication to specific ports on a target server, helping troubleshoot network configurations and firewall rules.

Features

• Dynamically prompts the user for:
  • Target server (IP address or hostname).
  • Number of ports to test.
  • Ports to check.
• Validates target server and port inputs.
• Uses PowerShell's built-in Test-NetConnection cmdlet for efficient and accurate testing.
• Provides clear results for each port: open or blocked.
• Includes instructions for simulating blocked ports using Windows Firewall rules.

Prerequisites

• A Windows system with PowerShell 5.1 or later installed.
• Optional: Administrator privileges for managing Windows Firewall rules, if we want to test blocked ports.

Usage

1. Clone the repository:

   ## Cloning the repository.

   ## Once cloned, we go to the location where the PowerShell script resides.
   ## Make sure you are able to execute PowerShell scripts.
   powershell -ExecutionPolicy Bypass -File .\check-outbound-ports.ps1
   ## Then execute :
   .\check-outbound-ports.ps1
