Tunneling in VPN refers to securely transmitting data across the internet by encapsulating it within another packet, resulting in a “tunnel.” This process ensures privacy and security by preventing unauthorized access to data during transmission. Common tunneling protocols include PPTP, L2TP, and OpenVPN, which help to ensure data confidentiality and integrity between the user’s device and the VPN server.
