What is the tunnel mode in networking? |
|
Answer» TUNNEL Mode is a way of transmitting data over the Internet that encrypts both the contents and the ORIGINAL IP address information. It secures communications between security gateways, firewalls, and other devices in a Site-to-Site VPN. In Transport Mode or Tunnel Mode, the Encapsulating Security Payload (ESP) is USED. ESP encrypts the data and the IP header information in Tunnel Mode. |
