What Is The Difference Between Transport And Tunnel Mode? |
|
Answer» Tunnel mode - Protects DATA in network-to-network or site-to-site SCENARIOS. It encapsulates and protects the entire IP packet—the payload including the original IP header and a new IP header (protects the entire IP payload including user data). Transport mode - Protects data in host-to-host or end-to-end scenarios. In transport mode, IPsec protects the payload of the original IP datagram by excluding the IP header (only protects the upper-layer protocols of IP payload (user data)). IPSec protocols AH and ESP can operate in either transport mode and tunnel mode. Tunnel mode - Protects data in network-to-network or site-to-site scenarios.
