Know what a VPN is and understand its use
A VPN “Virtual Private Network” means in English “Virtual Private Network”.
It allows them to be linked with another device connected to the internet, which means that they are under the same virtual local network. The devices must have a different IP address to differentiate them. If you wish, an article about the IP address is available at my-ip . The second device will act as a separator between the main device and the receiver ...
The main device will therefore send a request which will go through the second device (VPN), which will in turn be sent to the receiver without the latter knowing that the request comes from another device (than the second).
To put it simply, the second device that acts as a VPN replaces the main device as the sender of the request.
What does a VPN look like?
A VPN can therefore simply take the form of a router or a firewall to protect against external threats.
