IPsec VPN Modes - Tunnel Mode and Transport Mode. IPSec can be used to create VPN Tunnels to end-to-end IP Traffic (also called as IPSec Transport mode) or site-to-site IPSec Tunnels (between two VPN Gateways, also known as IPSec Tunnel mode). IPSec Tunnel mode: In IPSec Tunnel mode, the original IP packet (IP header and the Data payload) is encapsulated within another packet. Understanding VPN IPSec Tunnel Mode and IPSec Transport Tunnel mode is most commonly used between gateways (Cisco routers or ASA firewalls), or at an end-station to a gateway, the gateway acting as a proxy for the hosts behind it. Tunnel mode is used to encrypt traffic between secure IPSec Gateways, for example two Cisco routers connected over the Internet via IPSec VPN. IPsec modes: Understanding transport vs. tunnel modes for IPsec can actually operate in two different modes: IPsec tunnel mode and IPsec transport mode. Deciding which IPsec mode to use depends dramatically on your network topology and the purpose of your VPN. Tunnel Mode and Transport mode - VPN, Spam, Firewall
What is the difference between the Tunnel and Transport
The work of transport mode is to encrypt the message in the data packet and the tunneling mode encrypts the whole data packet. IPSec can also be used with other security protocols to improve the security system. Layer 2 Tunneling Protocol (L2TP): Transport mode and tunnel mode - IBM Transport is most often used in a host-to-host scenario, where the data endpoints and the security endpoints are the same. A transport mode encapsulated datagram is routed, or transported, in the same manner as the original packet. Figure 1 shows an IPv4 packet that is encapsulated using AH in transport mode… SSL VPN and IPsec VPN: How they work - Calyptix

Apr 15, 2019 The TCP/IP Guide - IPSec Modes: Transport and Tunnel Transport Mode: IP header, IPSec headers (AH and/or ESP), IP payload (including transport header). Tunnel Mode: New IP header, IPSec headers (AH and/or ESP), old IP header, IP payload. Again, this is a simplified view of how IPSec datagrams are constructed; the reality is significantly more complex.
