Why would I want to open a tunnel through my firewall?<\/p>\n

Suppose you have one service (HTTP, SSH, etc) in one specific computer (Laptop, RPi, etc) that is behind a firewall that prevents anyone from the Internet to get access to it and you need to share it with another device from outside the network.<\/p>\n

Go to NGROK [Link<\/a>] and create one account.<\/p>\n

Find the version of the system you want to share the service from.<\/p>\n

Copy the link and download the NGROK in the host machine.<\/p>\n

For a Linux 64 bits would be:<\/p>\n

wget https:\/\/bin.equinox.io\/c\/4VmDzA7iaHb\/ngrok-stable-linux-amd64.zip<\/pre>\n
For a Raspberry Pi would be:<\/p>\n
wget https:\/\/bin.equinox.io\/c\/4VmDzA7iaHb\/ngrok-stable-linux-arm.zip<\/pre>\n
In the host device, extract the zip content and insert the ‘authtoken<\/strong>‘ from your account:<\/p>\n
unzip ngrok*.zip\r\n.\/ngrok authtoken 1nGTE96CoM7lXK8A0e7FNvg4NiD_6FCzSWB6fV9pgjAHQafoh<\/pre>\n
Now just run the NGROK setting the method and the port of the service. Follow the example for an HTTP server running in the localhost:<\/p>\n
.\/ngrok http 80<\/pre>\n
One window will open with the public address that redirects the traffic through the tunnel to the host device.<\/p>\n
\"\"<\/p>\n
Copy and paste the generated address into a browser on any client computer to get access. As long as the NGROK still running the tunneled service will be available. Press CTRL + C to stop at any time.<\/p>\n
If you want to tunnel the SSH port issue the command:<\/p>\n
.\/ngrok tcp 22<\/pre>\n
For help:<\/p>\n
.\/ngrok help<\/pre>\n
\n
BONUS<\/strong><\/p>\n
Try out this open-source tunnel service written in Rust that replicates the core functionality of ngrok, RusTunnel<\/strong> [Link<\/a>].<\/p>\n
