(i) Transport mode (ii) Tunneling mode 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):

IPsec Tunnel vs Transport Mode-Comparison and Configuration R1(cfg-crypto-trans)#mode tunnel R1(cfg-crypto-trans) In our example above, we configure the VPN to work in “tunnel” mode. If we wanted to have “transport mode”, the command would be: R1(cfg-crypto-trans)#mode transport . We now proceed to create a crypto map called MyMap with sequence number 1. A crypto map can have multiple entries Solved: JunosPulse : SSL or ESP transport - Pulse Secure So, when a VPN client tries to establish a ESP tunnel, if there is anything which is blocking the ESP traffic, then the client auto-fallsback to SSL for compatibility seamlessly and the client is normally enabled to connect. ESP vs SSL mode is the transport mechanism between the client and the SA. Between the SA and the backend will the Types of Virtual Private Network (VPN) and its Protocols

Aug 06, 2019 Cisco ASA VPN "Tunnel Mode" / "Transport Mode" Solutions Tunnel mode also protects against traffic analysis; with tunnel mode, an attacker can only determine the tunnel endpoints and not the true source and destination of the tunneled packets, even if they are the same as the tunnel endpoints. When setting up a 'normal' site to site vpn the ASA uses tunnel mode.
