Network Address Translation (NAT)

NAT gives a virtual machine access to network resources using the host computer's IP address and a port through an internal Virtual Switch. 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. 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.) Additionally, NAT allows multiple virtual machines to host applications that require identical (internal) communication ports by mapping these to unique external ports.
