In flask

If on Eki's network, we will use ngrok (npm package), your MAC's internet sharing, and an SSH tunnel between a localhost:port to the IOT's webserver IP

ngrok http 5050
ssh -L5050:192.168.2.2:80 yourusername@localhost

This may require you to launch the SSH service before:

sudo launchctl load -w /System/Library/LaunchDaemons/ssh.plist

To stop it:

sudo launchctl unload  /System/Library/LaunchDaemons/ssh.plist
