NAT Type Checker Help Docs

Introduction

NAT Type Checker is built for practical work: open it, run the task, review the result, and move on without unnecessary setup.

Estimate NAT behavior from ICE candidate patterns using STUN/TURN probes. It is especially useful for developers, analysts, and hands-on users who need something fast, readable, and easy to verify.

In day-to-day use, the value comes from speed and clarity. You should be able to understand the result at a glance and decide what to do next.

What Is NAT Type Checker?

NAT Type Checker is designed to inspect a target, highlight useful signals, and make the result easier to review than a raw command-line output or scattered manual check. Estimate NAT behavior from ICE candidate patterns using STUN/TURN probes.

NAT Type Checker is primarily built around browser-first use, which keeps it lightweight for quick day-to-day tasks and one-off checks.

It is still evolving, so the core workflow is already useful, but the surrounding polish and edge-case handling may continue to improve over time.

Key Features

• Estimate NAT behavior from ICE candidate patterns using STUN/TURN probes. That gives users a clear starting point instead of a vague promise.
• NAT Type Checker surfaces the details people usually check manually, so you spend less time hunting through raw output and more time deciding what matters.
• NAT Type Checker keeps the workflow compact, which matters when a small job would otherwise turn into several tabs, copied snippets, or repeated manual edits.
• For common use cases, the workflow stays browser-first, which keeps the experience fast and reduces extra setup.

How to Use NAT Type Checker

1. Open NAT Type Checker and enter the target input, such as a domain, URL, host, token, or payload.
2. Start the check and wait for the analysis to complete.
3. Review the returned details carefully instead of stopping at the top-level status alone.
4. Use the findings to make a fix, confirm a hypothesis, or document what you found.
