Tunnel mode VPN and Transport mode VPN - Check Point
SSL VPN and IPsec VPN: How they work - Calyptix Nov 02, 2016 The TCP/IP Guide - IPSec Modes: Transport and Tunnel Key Concept: IPSec has two basic modes of operation.In transport mode, IPSec AH and/or ESP headers are added as the original IP datagram is created; this mode is associated with integrated IPSec architectures.In tunnel mode, the original IP datagram is created normally, then the entire datagram is encapsulated into a new IP datagram containing the AH/ESP IPSec headers.

Understanding VPN IPSec Tunnel Mode and IPSec Transport Understanding IPSec Modes –Tunnel Mode & Transport Mode. IPSec can be configured to operate in two different modes, Tunnel and Transport mode. Use of each mode depends on the requirements and implementation of IPSec. IPSec Tunnel Mode. IPSec tunnel mode is the default mode. With tunnel mode, the entire original IP packet is protected by IPSec. IPsec VPN Modes - Tunnel Mode and Transport Mode IPSec Tunnel mode is most widely used to create site-to-site IPSec VPN. IPSec Transport mode: In IPSec Transport mode, only the Data Payload of the IP datagram is secured by IPSec. IP Header is the original IP Header and IPSec inserts its header between the IP header and the upper level headers. IPSec Transport mode can be used when encrypting What is the difference between the Tunnel and Transport Transport mode: The transport mode encrypts only the payload and ESP trailer; so the IP header of the original packet is not encrypted. The IPsec Transport mode is implemented for client-to-site VPN scenarios. NAT traversal is not supported with the transport mode. MSS is higher, when compared to Tunnel mode, as no additional headers are required.
