How to forward traffic with ngrok?

ngrok is a special software that allows forwarding traffic through a public URL. It is really convenient for creating a public endpoint for any kinds of development as it is modern alternative to VPN. Our customers use ngrok when they want to help us with implementation of their ASIC machine. With ngrok you can open access to one machine for our tech team and close it when development is finished.

In this tutorial we will show you how to create access to one of your ASIC machines with ngrok.

First, you will need an account at ngrok, which you can get by registering.

You will receive confirmation e-mail to your e-mail address. Once you confirm your e-mail, you will need to find your access token. Navigate to Getting start > Your Authtoken and a website with your token will open up.

Let's say that your authtoken TOKEN is

and your ASIC's local IP is

We will be connecting to:

Next step is to open connection through any device that you are more comfortable with and is in the same local network as your ASIC machine.

1. Download ngrok for Windows from here.
2. Unzip ngrok-stable-windows-amd64.zip
3. Copy ngrok.exe to C:\Users\your_computer_username
4. Press Windows key or navigate to search field and search for cmd.exe
5. Press [Enter] to open CMD

To run ngrok enter the following two commands to your CMD windows.

Once you establish the connection with last command, you should see similar response to:

The one under line "Forwarding" is the one you share with our team.

The screen needs to be running while we are adding implementation.

Once we are done with the implementation, you can close the screen down with Ctrl+C and connection to your machine will be terminated.
