Issue/Introduction

VMware Lab Platform vApp Networks 

vApp networks allow virtual machines to communicate with each other or by connecting to an organization's virtual data center network to virtual machines in other vApps. 

Every vApp contains a vApp network. The network is created when the vApp is deployed and deleted when the vApp is undeployed. 

The vApp network can be nat-ed to an Organization VDC Network, (Default behavior of Lab builder) in order to provide internet access to the VMs in a particular vApp. 

You can add networks of different types to a vApp to address multiple networking scenarios. 

Virtual machines in the vApp can connect to the networks that are available in a vApp. If you want to connect a virtual machine to a different network, you must first add this network to the vApp.

Symptoms:

• Virtual machines fail to connect to the internet
• There is no network connectivity between virtual machines
