Tunnel mode: A mode of operation in IPsec where both the header and the payload of the IP packet are protected during transmission. This mode is commonly used in VPNs (Virtual Private Networks) as it allows a network device to act as an intermediary, encapsulating and encrypting all traffic passing through it.
