About This Tool

The VPC Endpoint Reachability Analyzer is a tool designed to help AWS users simulate and analyze connectivity between VPC components (like subnets, security groups, and route tables) and VPC endpoints. By inputting your VPC ID, subnet IDs, security group IDs, route table IDs, and endpoint service name, the tool performs a reachability analysis to check if traffic can flow correctly, helping you identify misconfigurations or blockages in your cloud network setup. It provides detailed results including connectivity status, path information, and recommendations for fixes.

How to Use

  1. Enter your AWS VPC ID in the first input field.
  2. Provide subnet IDs (comma-separated) that you want to analyze for reachability.
  3. Input security group IDs (comma-separated) associated with the VPC.
  4. Add route table IDs (comma-separated) used in the VPC.
  5. Specify the endpoint service name (e.g., com.amazonaws.vpce.us-east-
  6. vpce-svc-
  7. .
  8. Click the 'Analyze Reachability' button to run the simulation.
  9. View the results showing connectivity status, detailed path analysis, and any issues found.

Frequently Asked Questions

Find Quick Answers

What is a VPC endpoint reachability analysis?
It's a simulation to check if network traffic can successfully travel from components within your AWS VPC (like subnets) to a specified VPC endpoint, based on configurations like security groups and route tables.
Do I need AWS credentials to use this tool?
No, this tool runs entirely in your browser or on the server without requiring AWS credentials. It simulates reachability based on the IDs you provide.
What happens if I leave a field empty?
All fields are required for accurate analysis. The tool will validate inputs and show an error message if any field is missing or invalid.
Can this tool fix connectivity issues?
No, it only analyzes and identifies potential issues. You'll need to apply the recommendations manually in your AWS console.
