7 Useful Free Linux Network Tunnels

Tunneling is a way to cross terrain or boundaries that cannot normally be crossed.

Similarly, in networking, tunnels are a method for discretely transmitting data across a network using protocols that are not supported by that network. Tunneling works by encapsulating packets: wrapping packets inside of other packets. Tunneling involves six key processes: encryption, encapsulation, header addition, transmission, decapsulation, and decryption.

Network tunnels provide a direct connection between a remote server and the local network, and the transmission of data is undetectable by the public network.

One big advantage of tunneling is that it allows remote workers and field teams to safely work offsite without compromising personal or organizational security. Other practical use cases include remote support, disaster recovery, safe supply chain management, network monitoring, and more.
