In this article, we will learn how to set up a HTTP tunnel between a PC and a Linux server with the SSH protocol to secure our transactions through a firewall or another.
Before to begin any technical part, I will try to explain the operation of Port Forwarding and why implement it.
To understand this concept, I refresh your memories on the communication of computer:
To exchange informations, computers need an IP address and a port number. The port number is important because it’s thanks to it that the communication exists. Client and server have to communicate on the same port number.
Now, we decrypt the Port Forwarding. The Port Forwarding consist of redirect informations sent on a port number of a computer to a different port number on another computer.
