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

IPsec Tunnel vs Transport Mode-Comparison and Configuration

(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):

A good practice is to run IPsec tunnel mode to obtain the best possible security encryption, while ensuring corporate headquarters uses VPN hardware acceleration. This will help alleviate the burden of VPN processing and ensure VPN performance is at its maximum peak! For more information, view SearchEnterpriseWAN.com's VPN tutorial.
