How is “tunneling” accomplished in a VPN?

  • New headers from one or more VPN protocols encapsulate the original packets.
  • All packets between two hosts are assigned to a single physical medium to ensure that the packets are kept private.
  • Packets are disguised to look like other types of traffic so that they will be ignored by potential attackers.
  • A dedicated circuit is established between the source and destination devices for the duration of the connection.
    Answers Explanation & Hints:

    The two primary protocols used with IPsec are AH and ESP. AH is protocol number 51 and provides data authentication and integrity for IP packets that are exchanged between the peers. ESP, which is protocol number 50, performs packet encryption.
