Add a network to an organization vDC to enable its virtual machines to communicate with each other or to provide access to the Internet. A single organization vDC can have multiple networks.

Types of Organization vDC Networks and Their Requirements

Organization vDC Network Type

Description

Requirements

External organization vDC network - direct connection

Accessible by multiple organizations. Virtual machines belonging to different organizations can connect to and see traffic on this network.

This network provides direct layer 2 connectivity to machines outside of the organization. Virtual machines outside of this organization can connect to virtual machines within the organization directly.

External network

External organization vDC network - NAT-routed connection

Accessible only by this organization. Only virtual machines within this organization can connect to this network.

This network also provides controlled access to an external network. System administrators and organization administrators can configure network address translation (NAT) and firewall settings to make specific virtual machines accessible from the external network.

On the Org vDC Networks tab, NAT-routed networks display a gateway address.

vSphere Edge 5.1 and an edge gateway

Internal organization vDC network

Accessible only by this organization. Only virtual machines within this organization can connect to and see traffic on this network.

This network provides an organization with an isolated, private network that multiple vApps can connect to. This network provides no connectivity to virtual machines outside this organization. Machines outside of this organization have no connectivity to machines within the organization.

On the Org vDC Networks tab, internal networks do not display an associated gateway address.
