Description
The IP Forwarding feature enables the Virtual Machine (VM) associated with the NIC attached, to receive network traffic not destined for one of the IP addresses assigned to any of the IP configurations assigned to the network interface, and to send network traffic with a different source IP address than the one assigned to one of a network interface's IP configurations. Therefore, IP forwarding must be enabled only for network interface that is attached to the virtual machine that need to forward traffic.
