Figure 95 VPN for Configuration Provisioning Advanced Wizard: Scenario Settings
IKE (Internet Key Exchange) Version: IKE is a protocol used in security associations to send data securely.
IKE uses certificates or pre-shared keys for authentication and a Diffie–Hellman key exchange to set up
a shared session secret from which encryption keys are derived.
IKEv2 supports Extended Authentication Protocol (EAP) authentication, and IKEv1 supports X-Auth. EAP is
important when connecting to existing enterprise authentication systems.
Rule Name: Type the name used to identify this VPN connection (and VPN gateway). You may use 1-31
alphanumeric characters, underscores (_), or dashes (-), but the first character cannot be a number.
This value is case-sensitive.
Application Scenario: Only the Remote Access (Server Role) is allowed in this wizard. It allows incoming
connections from the Zyxel Device IPSec VPN Client.
