Explanation:

RAS Gateway – Multitenant. You can deploy RAS Gateway as a multitenant, software-based edge gateway and router when you are using Hyper-V Network Virtualization or you have VM networks deployed with virtual Local Area Networks (VLANs). With the RAS Gateway, Cloud Service Providers (CSPs) and Enterprises can enable datacenter and cloud network traffic routing between virtual and physical networks, including the Internet. With the RAS Gateway, your tenants can use point-so-site VPN connections to access their VM network resources in the datacenter from anywhere. You can also provide tenants with site-to-site VPN connections between their remote sites and your CSP datacenter. In addition, you can configure the RAS Gateway with BGP for dynamic routing, and you can enable Network Address Translation (NAT) to provide Internet access for VMs on VM networks.
