Tunneling

Tunneling is a method used in networking to encapsulate one type of network protocol within another protocol’s packets. This allows data to be securely transmitted over an incompatible network or through a network with restricted access. Tunneling is commonly used in Virtual Private Networks (VPNs) to create secure connections over public networks. By encapsulating data packets, tunneling provides a means to bypass firewalls, enhance security, and enable the use of protocols not supported by the underlying network infrastructure.
