Raspberry Pi - Network Tunnel

I plan to use a number of different web utilites that will require my Raspberry Pi to temporarily be available from the Internet. One of the easiest methods that I’ve found is to use “ngrok” to provide a secure tunnel. To expose an http service on a particular port, execute the program with the protocol and port:

ngrok command
./ngrok http 1880

This example will allow you to use Node-Red to develop a web service on your Raspberry Pi that can be used as a webhook on an Amazon Echo Alexa skill.
