This word first occurs as given to Abram by the Canaanites, (Genesis 4:13) because he had crossed the Euphrates. The name is also derived from Eber, beyond, on the other side, Abraham and his posterity being called Hebrews in order to express a distinction between the races east and west of the Euphrates.
Network isolation. To configure a virtual machine to have complete network isolation, each virtual machine must be assigned to only one internal virtual network. The virtual network must be configured so that it does not use a physical network adapter. For more information about how to configure a virtual network, see Create a virtual network.
Wireless isolation was commonly used for securing guest networks from accessing one's internal network/client/servers from a SINGLE shared router... but different manufacturer will implement it slightly different from one another.
