Chart Title External (NAT) Provider Address Host-Cluster Host-LiveMigration Host-Management Tenant B Tenant A Percentage Utilized Assigned Addresses Utilized Addresses 20. This chart can then be altered as required within Excel and utilized in other applications as required. This can include colors, width, height, and so on. VMM UTILIZED IP ADDRESSES External (NAT) Provider Address Host-Cluster Host-LiveMigration Host-Management Tenant B Tenant A Percentage Utilized Assigned Addresses Utilized Addresses How it works As IPAM has all of the available data from VMM, it can be used to monitor IP address usage in VMM defined networks. It is possible to use PowerShell to export the data from IPAM. Excel is capable of providing rich data visualizations and can give you the ability to slice data as appropriate. This can lead to high-quality management information reporting. Windows Server Gateway Configuration In this chapter, we will cover the following recipes: Network Address Translation (NAT) with the gateway Direct Routing and how it is different from NAT Introduction Windows Server 2012 R2 includes an inbox gateway solution for Hyper-V Network Virtualization (HNV) within the Routing and Remote Access server role. As HNV uses the NVGRE protocol, a gateway server must be able to understand the protocol and undertake the required functions. If a gateway is configured to use Network Address Translation (NAT), it will mask the internal HNV network behind the NAT interface. If a gateway is configured for Direct Routing, then it will perform the decapsulation of network packets leaving an HNV network and also the encapsulation of data entering an HNV network. Network Address Translation with the gateway In Chapter 3, Creating the Gateway for Virtual Machine Communications, you created a Windows Server Gateway so that VMs could access
