Settings that control authentication.

The ChildSecurityAssociationParameters dictionaries.

If true, the system disables MOBIKE.

If true, the system disables IKEv2 redirect. If not set, the system redirects an IKEv2 connection when it receives a redirect request from the server.

If true, the system performs a certificate revocation check for IKEv2 connections. This is a best-effort revocation check and server response timeouts won’t cause it to fail.

If true, enables NAT keepalive offload for Always On VPN IKEv2 connections. The device sends keepalive packets to maintain NAT mappings for IKEv2 connections that have a NAT on the path. It sends keepalive packets at regular intervals when the device is awake. If NATKeepAliveOffloadEnable is true, the system offloads keepalive packets to hardware while the device is asleep.

NAT keepalive offload has an impact on the battery life due to the extra workload during sleep. The default interval for the keepalive offload packets is 20 seconds over Wi-Fi and 110 seconds over Cellular interface. The default NAT keepalive works well on networks with small NAT mapping timeouts but imposes a potential battery impact. If a network has larger NAT mapping timeouts, larger keepalive intervals may be safely used to minimize battery impact. Modify the keepalive interval through the NATKeepAliveInterval key.

If true, enables Perfect Forward Secrecy (PFS) for IKEv2 Connections.

If set to true, the device doesn’t allow DES, 3DES, and Diffie-Hellman groups less than 14. Also the device requires the encryption algorithm specified in IKESecurityAssociationParameters to be at least as cryptographically strong as the algorithm specified in ChildSecurityAssociationParameters. The device rejects this configuration if these requirements aren’t met.

The IP address or hostname of the VPN server.

Specifies details about how the system handles idle VPN connections.

These parameters apply to Child Security Association unless ChildSecurityAssociationParameters is specified.

Identifier of the IKEv2 client.

The Maximum Transmission Unit (MTU) specifies the maximum size in bytes of each packet that the system sends over the IKEv2 VPN interface.

The NAT Keepalive interval for Always On VPN IKEv2 connections. This value controls the interval that the device sends keepalive offload packets. The minimum value is 20 seconds. If no key is specified, the default is 20 seconds over Wi-Fi and 110 seconds over a cellular interface.

Post Quantum Key Exchange settings.

The remote identifier.

If true, negotiations should use IKEv2 Configuration Attribute INTERNAL_IP4_SUBNET and INTERNAL_IP6_SUBNET.
