Jul 16, 2018 · A virtual private network, or VPN, allows you to securely encrypt traffic as it travels through untrusted networks, such as those at the coffee shop, a conference, or an airport. IKEv2, or Internet Key Exchange v2, is a protocol that allows for direct IPSec tunneling between the server and client. In IKEv2 VPN implementations, IPSec provides
In phase 1, an IPsec node initializes the connection with the remote node or network. The remote node/network checks the requesting node's credentials and both parties negotiate the authentication method for the connection. On Red Hat Enterprise Linux systems, an IPsec connection uses the pre-shared key method of IPsec node authentication.
