The scheme above roughly describes how devices with private IP addresses communicate with a remote host on the Internet with the help of NAT. Bellow the scheme is a depiction of a NAT table. It illustrates how the router differentiates to which device in the local network to redirect incoming data.

The scheme above roughly describes how devices with private IP addresses communicate with a remote host on the Internet (and ''vice versa'') with the help of NAT. Bellow the scheme is a depiction of a NAT table. It illustrates how the router differentiates to which device in the local network to redirect incoming data packets.
