How To Setup Port Forwarding For Msfvenom Android Payloads (WAN)

What is Ngrok?

Ngrok is a tunneling, reverse proxy system that establishes secure tunnels from a public endpoint such as the internet to a locally running network service while capturing all traffic for detailed inspection and replay.

So it allows you to expose a port on your computer on the internet, and because it is a reverse proxy it does not expose your IP, it provides you with a URL.

It is most popularly used by Web developers, exposing their local host/web server on the internet to share with others or test.

Issues with traditional Port forwarding

  • Many individuals have a static IP or have only one IP assigned to them by their ISP.
  • Do not have access to their router admin page – I have made a video on how to do this manually.
  • Real port forwarding exposes your computer completely, with your IP
