Modifies the configurations of an IPsec server.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes UpdateIpsecServer

The operation that you want to perform. Set the value to UpdateIpsecServer.

RegionId String Yes cn-shanghai

The ID of the region where the IPsec server is created.

You can call the DescribeRegions operation to query the most recent region list.

IpsecServerId String Yes iss-bp1bo3xuvcxo7ixll****

The ID of the IPsec server.

LocalSubnet String No 192.168.0.0/24,172.17.0.0/16

The local CIDR blocks, which refer to the CIDR blocks on the virtual private cloud (VPC) side.

Separate multiple CIDR blocks with commas (,). Example: 192.168.1.0/24,192.168.2.0/24.

ClientIpPool String No 10.0.0.0/24

The client CIDR block. It refers to the CIDR block that is used to allocate an IP address to the client.

Note The client CIDR block must not overlap with the CIDR blocks on the VPC side.
IpsecServerName String No test

The name of the IPsec server.

The name must be 2 to 128 characters in length, and can contain letters, digits, underscores (_), and hyphens (-). The name must start with a letter.

EffectImmediately Boolean No false

Specifies whether to delete the current IPsec tunnel and reinitiate negotiations. Valid values:

  • true: initiates negotiations after the configuration is completed.
  • false (default): initiates negotiations when inbound traffic is detected.
IkeConfig String No null

The configuration of Phase 1 negotiations. Valid values:

  • IkeVersion: the IKE version. Valid values: ikev1 and ikev2. Default value: ikev2.
  • IkeMode: the IKE negotiation mode. Default value: main.
  • IkeEncAlg: the encryption algorithm that is used in Phase 1 negotiations. Default value: aes.
  • IkeAuthAlg: the authentication algorithm that is used in Phase 1 negotiations. Default value: sha1.
  • IkePfs: the Diffie-Hellman key exchange algorithm that is used in Phase 1 negotiations. Default value: group2.
  • IkeLifetime: the SA lifetime determined by Phase 1 negotiations. Unit: seconds. Valid values: 0 to 86400. Default value: 86400.
  • LocalId: the identifier of the IPsec server. The value can be a fully qualified domain name (FQDN) or an IP address. By default, the ID of the IPsec server is the public IP address of the VPN gateway.
  • RemoteId: the identifier of the peer. The value can be an FQDN or an IP address. The default value is empty.
IpsecConfig String No null

The configuration of Phase 2 negotiations. Valid values:

  • IpsecEncAlg: the encryption algorithm that is used in Phase 2 negotiations. Default value: aes.
  • IpsecAuthAlg: the authentication algorithm that is used in Phase 2 negotiations. Default value: sha1.
  • IpsecPfs: forwards packets of all protocols. The Diffie-Hellman key exchange algorithm used in Phase 2 negotiations. Default value: group2.
  • IpsecLifetime: the SA lifetime determined by Phase 2 negotiations. Unit: seconds. Valid values: 0 to 86400. Default value: 86400.
PskEnabled Boolean No true

Specifies whether to enable pre-shared key authentication. If you set the value to true, pre-shared key authentication is enabled.

Psk String No Cfd123****

The pre-shared key.

Enter the pre-shared key that is used for identity authentication between the IPsec server and the client. The key must be 1 to 100 characters in length.

If you do not specify a pre-shared key, the system randomly generates a 16-bit string as the pre-shared key. You can call the ListIpsecServers operation to query the pre-shared keys that are generated by the system.

Note The pre-shared key of the IPsec server must be the same as the authentication key of the client. Otherwise, a connection cannot be established between the IPsec server and the client.
ClientToken String No e4567-e89b-12d3-a456-42665544****

The client token that is used to ensure the idempotence of the request.

You can use the client to generate the value, but you must make sure that it is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length.

Note If you do not set this parameter, the system automatically uses RequestId as ClientToken. RequestId may be different for each API request.
DryRun String No false

Specifies whether to only precheck this request. Valid values:

  • true: only prechecks the request. After the request passes the precheck, the system does not modify the configurations of the IPsec server. The system prechecks whether the required parameters are set, whether the values are in valid formats, and the service limits. If the request fails to pass the precheck, a corresponding error code is returned. If the request passes the precheck, the DryRunOperation error code is returned.
  • false (default): prechecks the request. After the request passes the precheck, the system modifies the configurations of the IPsec server.

Response parameters

Parameter Type Example Description
RequestId String B61C08E5-403A-46A2-96C1-F7B1216DB10C

The ID of the request.
