When you do not want the virtual machines in a vApp to connect to objects outside the vApp, you must create an isolated vApp network.

Verify that you are connected to a vCloud Director server.


Retrieve the vApp for which you want to create a vApp network.

$myVApp = Get-CIVApp -Name 'MyVApp'

Create the new vApp network with a selected gateway and network mask.

New-CIVAppNetwork -VApp $myVApp -Name 'MyVAppInternalNetwork' -Routed -Gateway '' -Netmask '' -ParentOrgVdcNetwork $null

By default, the vApp network has an enabled firewall.
