Citrix SaaS Gateway Service Workflow:

Before you begin to use the SaaS Gateway Service, ensure that the following steps are completed:

  1. Have a 410-SE platform edition appliance with SD-WAN release version 9.3.3 or higher.

  2. Perform the single step upgrade procedure to install the software version that supports SaaS Gateway Service.

  3. Configure MCN appliance and setup 410-SE branch appliance:

    • Enable SaaS Gateway Service in the 410-SE appliance SD-WAN GUI.

    • Perform change management process on the MCN appliance:

    • Create Intranet Service or use existing Intranet Service. It is recommended to configure two WAN links, with one as primary and other as secondary.

    • Create Application object for application based routes.

    • Create Application routes or IP based routes for a selected SaaS application.

Configure the MCN and branch (410-SE) site appliances.

  • Primary MCN: The primary Master Control Node of the SD-WAN network. The MCN is responsible for managing the SD-WAN configurations and software versions for all the clients and serves as a mediator between clients.

  • Client: A client receives its appliance configuration from an MCN and participates in the SD-WAN network as described by the Configuration.

To configure 410-SE appliance to use Citrix SaaS Gateway Service:
