You can add an organization virtual datacenter network to a vApp to make the network available to virtual machines in the 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 datacenter's network pool. An edge gateway is created and attached to the isolated network and the organization virtual datacenter network. Traffic going to and from the virtual machines pass through the edge gateway, which translates the IP address using NAT and proxy-AR, which allows a router to pass traffic between two networks using the same IP space.
