Tunneling methods

Tunneling methods are techniques used in computer networks to securely carry data across the internet by encapsulating it within other data packets. Imagine sending a confidential message inside a secure envelope, which is then placed inside a regular envelope for transportation. This process allows data to bypass restrictions or monitoring, maintaining privacy and security. Tunneling is commonly used in Virtual Private Networks (VPNs) to connect remote users to a private network safely, providing encryption and concealment of the original data, so only authorized parties can access the information.
