The cmdlet specifies an IKEv2 tunnel. If IPsec is required to protect traffic from hosts behind the IPsec peers, tunnel mode must be used. – Interface for IPsec tunnel – The IPsec tunnel should be formed using the loopback interface IP. In this example, we will set up IPSEC to encrypt communications between two windows machines. Ce document donne un exemple de gestion de réseau qui simule le fusionnement de deux sociétés avec le même schéma d'adressage IP. To configure IPSec we need to setup the following in order: Create extended ACL; Create IPSec Transform; Create Crypto Map; Apply crypto map to the public interface; Let us examine each of the above steps. the incoming packet. This is a great configuration if you want to tunnel some traffic between two trusted networks. IKEv2 tunnels using certificates and pre-shared keys.
