If you are interested you can download the tool from:
There is a version available for Mac, Windows, Linux and ARM. The program is really simple to use. On the Mac you simply unzip and run by running ./ngrok from the terminal. This then gives the following output:
ngrok (Ctrl+C to quit) Tunnel Status online Version 1.7/1.6 Forwarding http://<address>.ngrok.com -> 127.0.0.1:80 Forwarding https://<address>.ngrok.com -> 127.0.0.1:80 Web Interface 127.0.0.1:4040 # Conn 0 Avg Conn Time 0.00ms
Then you simply go to the address listed and you will be forwarded on to your machine on port 80. Note I have removed the address above.
From reading the documentation ngrok gets much cooler. It will give you a full detailed log of everything it’s captured on http://localhost:4040, allow you to replay requests, capture requests, forward requests on to another machine on the network and much more.
