You can deploy VMware Tunnel using the Unified Access Gateway appliance. Unified Access Gateway supports deployment on either ESXi or Microsoft Hyper-V environments. VMware Tunnel provides a secure and effective method for individual applications to access corporate resources. Content Gateway (CG) is a component of the VMware AirWatch Content Management solution that securely allows access to On-Premise repository content on mobile devices.

DNS Requirements for VMware Tunnel and Content Gateway

When VMware Tunnel and Content Gateway services are enabled on the same appliance, and TLS Port Sharing is enabled, the DNS names must be unique for each service. When TLS is not enabled only one DNS name can be used for both services as the port will differentiate the incoming traffic.
