What does tunnel mode do?

Explanation:
Tunnel mode secures by wrapping the entire original IP datagram inside an encrypted payload and then placing it inside a new outer IP header. This means both the header of the original packet and its payload are encrypted and protected as it travels, while a new outer header is used for routing. In short, the whole packet goes through confidentiality protection, not just the payload or a signature, which is why tunnel mode encrypts the entire packet.
