Tunnel mode is most commonly used between gateways, or at an end-station to a gateway, the gateway acting as a proxy for the hosts behind it. Transport mode is used between end-stations or between an end-station and a gateway, if the gateway is being treated as a host—for example, an encrypted Telnet session from a workstation to a router, in
CCNA Security Chapter 8 Exam v2 - ICT Community In order to bring up an IPsec tunnel, an access list must be configured with a permit statement that will identify interesting traffic. Once interesting traffic is detected by matching the access list, the tunnel security associations can be negotiated. Transport and Tunnel Modes in IPsec - Oracle Solaris In tunnel mode, the inner IP packet determines the IPsec policy that protects its contents. In transport mode, the outer header, the next header, and any ports that the next header supports, can be used to determine IPsec policy. In effect, IPsec can enforce different transport mode policies between two IP addresses to the Which of the following are differences between IPsec main

IPSec functions in two modes. Tunnel mode and transport mode. Tunnel mode is when IPSec is the protocol that is used for tunneling and for encapsulation. This is the case when we configure the following: tunnel mode ipsec ipv4 tunnel protection ipsec profile profile_name where the profile as shown in the lesson chooses to use the tunnel mode Tunnel Mode - Win32 apps | Microsoft Docs The Tunnel Mode IPsec policy scenario is used to apply IPsec tunnel mode protection for all matching traffic between two tunnel endpoints. This policy scenario is typically used to protect traffic between multiple branch-office subnets, when it gets forwarded between the corresponding gateways on … IPsec tunnel interface - Keepalive - Cisco Community Nov 15, 2016
