Basically, a NAT uses a flow table to route traffic from an external (host) IP Address and port number to the correct internal IP address associated with an endpoint on the network (virtual machine, computer, container, etc.)Īdditionally, NAT allows multiple virtual machines to host applications that require identical (internal) communication ports by mapping these to unique external ports.įor all of these reasons, NAT networking is very common for container technology (see Container Networking). Network Address Translation (NAT) is a networking mode designed to conserve IP addresses by mapping an external IP address and port to a much larger set of internal IP addresses. NAT gives a virtual machine access to network resources using the host computer's IP address and a port through an internal Hyper-V Virtual Switch. For additional details on the Windows NAT (WinNAT) implementation, capabilities, and limitations, please reference the WinNAT capabilities and limitations blog NAT Overview
Note: Currently, you are limited to one NAT network per host.
Windows 10 Hyper-V allows native network address translation (NAT) for a virtual network.
