You can add a network to a vApp to make the network available to the virtual machines in the vApp. You can add a vApp network or an organization virtual data center network to a vApp.

Connections can be direct or fenced. Fencing allows identical virtual machines in different vApps to be powered on without conflict by isolating the MAC and IP addresses of the virtual machines.

When fencing is enabled and the vApp is powered on, an isolated network is created from the organization virtual data center network pool. An edge gateway is created and attached to the isolated network and the organization virtual data center network. Traffic going to and from the virtual machines pass through the edge gateway, which translates the IP address using NAT and proxy-AR. This allows a router to pass traffic between two networks by using the same IP space.


To add an organization virtual data center network, your administrator must have created such a network.


  1. On the Virtual Datacenters dashboard screen, click the card of the virtual data center you want to explore, and select vApps from the left panel.
  2. Click Card Icon to view the vApps in a card view.
