VMware allows the Enterprise users to define and configure a Non SD-WAN Destination instance in order to establish a secure IPSec tunnel directly from an SD-WAN Edge to a Non SD-WAN Destination. This section also allows you to configure Cloud Security Services.

Procedure

  1. In the Enterprise portal, go to Configure > Network Services, and then under Non SD-WAN Destinations, expand Non SD-WAN Destinations via Edge.
    1. In the Non SD-WAN Destinations via Edge area, click New or New NSD via Edge option to create a new Non SD-WAN Destination.
      Note: The New NSD via Edge option appears only when there are no items in the table.
    2. Following configuration options are available:
      Option Description
      General
      Service Name Enter a name for the Non SD-WAN Destination. This field is mandatory.
      Service Type Select the service type from the drop-down menu. The available options are Generic IKEv1 Router (Route Based VPN), Generic IKEv2 Router (Route Based VPN), and Microsoft Azure Virtual Wan. This field is mandatory.
      Tunnel mode Select a tunnel mode from the drop-down menu. The available options are Active/Active, Active/Hot-Standby, and Active/Standby.
      IKE/IPSec Settings
      IP Version Displays the IP version of the current Non SD-WAN Destination.
      Primary VPN Gateway
      Public IP Enter a valid IPv4 or IPv6 address. This field is mandatory.
      View advanced settings for IKE Proposal: Expand this option to view the following fields.
      Encryption Select the AES algorithm key size from the drop-down list, to encrypt data. The available options are AES 128, AES 256, AES 128 GCM, AES 256 GCM, and Auto. The default value is AES 128.
      DH Group Select the Diffie-Hellman (DH) Group algorithm from the drop-down list. This is used for generating keying material. The DH Group sets the strength of the algorithm in bits. The supported DH Groups are 2, 5, 14, 15, 16, 19, 20, and 21. The default value is 14.
      Hash Select one of the following supported Secure Hash Algorithm (SHA) functions from the drop-down list:
      • SHA 1
      • SHA 256
      • SHA 384
        Note: This value is not available for the Microsoft Azure Virtual Wan Service Type.
      • SHA 512
        Note: This value is not available for the Microsoft Azure Virtual Wan Service Type.
      • Auto

      The default value is SHA 256.
      IKE SA Lifetime(min) Enter the time when Internet Key Exchange (IKE) rekeying is initiated for Edges. The minimum IKE lifetime is 10 minutes and maximum is 1440 minutes. The default value is 1440 minutes.
      Note: Rekeying must be initiated before 75-80 % of lifetime expires.
      DPD Timeout(sec) Enter the DPD timeout value. The DPD timeout value will be added to the internal DPD timer, as described below. Wait for a response from the DPD message before considering the peer to be dead (Dead Peer Detection).
      Prior to the 5.1.0 release, the default value is 20 seconds. For the 5.1.0 release and later, see the list below for the default value.
      • Library Name: Quicksec
      • Probe Interval: Exponential (0.5 sec, 1 sec, 2 sec, 4 sec, 8 sec, 16 sec)
      • Default Minimum DPD Interval: 47.5sec (Quicksec waits for 16 seconds after the last retry. Therefore, 0.5+1+2+4+8+16+16 = 47.5).
      • Default Minimum DPD interval + DPD Timeout(sec): 67.5 sec
      Note: Prior to the 5.1.0 release, you can deactivate DPD by configuring the DPD timeout timer to 0 seconds. However, for the 5.1.0 release and later, you cannot deactivate DPD by configuring the DPD timeout timer to 0 seconds. The DPD timeout value in seconds will get added onto the default minimum value of 47.5 seconds).

      Encryption Select the AES algorithm key size from the drop-down list, to encrypt data. The available options are None, AES 128, and AES 256. The default value is AES 128.
      PFS Select the Perfect Forward Secrecy (PFS) level for additional security. The supported PFS levels are 2, 5, 14, 15, 16, 19, 20, and 21. The default value is 14.
      Hash Select one of the following supported Secure Hash Algorithm (SHA) functions from the drop-down list:
      • SHA 1
      • SHA 256
      • SHA 384
        Note: This value is not available for the Microsoft Azure Virtual Wan Service Type.
      • SHA 512
        Note: This value is not available for the Microsoft Azure Virtual Wan Service Type.

      The default value is SHA 256.
      IPsec SA Lifetime(min) Enter the time when Internet Security Protocol (IPsec) rekeying is initiated for Edges. The minimum IPsec lifetime is 3 minutes and maximum is 480 minutes. The default value is 480 minutes.
      Note: Rekeying must be initiated before 75-80 % of lifetime expires.
      Secondary VPN Gateway
      Add - Click this option to add a secondary VPN Gateway. Following fields are displayed.
      Public IP Enter a valid IPv4 or IPv6 address.
      Remove Deletes the Secondary VPN Gateway.
