Configuration overview for Ivanti Tunnel for the Samsung Knox container (Ivanti EPMM)

Configuration for Ivanti Tunnel VPN is done in the Ivanti EPMM Admin Portal. Do the following to setup Ivanti Tunnel in the Samsung Knox container:

  1. Configuring an IP_ANY AppTunnel service on a Standalone Sentry.
  2. Creating Ivanti Tunnel VPN configuration for Samsung Knox Workspace (Ivanti EPMM).
  3. Distributing Ivanti Tunnel through [email protected].
  4. Configuring app VPN in the Samsung Knox container.

The VPN configuration for Ivanti Tunnel is done in two separate configurations in the Ivanti EPMM Admin Portal: the VPN configuration for Tunnel (Samsung Knox Workspace) and the Samsung KNOX Container configuration. The Ivanti Tunnel for Samsung Knox workspace VPN configuration sets the DNS and app behavior. The Samsung Knox container configuration determines whether the VPN configuration is applied per-app individually or to all apps in the container (per-container).

The VPN configuration also determines whether the connection is always-on or on-demand. With always-on VPN, Ivanti Tunnel is started when the Samsung Knox Workspace starts, and the connection stays on. Traffic from an app in the Knox Workspace can go through the Ivanti Tunnel VPN. With on-demand VPN, a Tunnel VPN connection is started when an app that uses Tunnel is launched, and the connection stays on till the last app that can use the Tunnel VPN is killed.

Ivanti Tunnel must be available in the Samsung Knox Workspace. Sometimes an app can be available in the Knox container as well as outside the container. Only the app in the Knox container can use Tunnel.

The following table describes Tunnel behavior depending on the combination of whether VPN is on-demand or always-on and if the VPN configuration is applied per-app or per-container.
