VMware® Lab Manager User's Guide Fencing Options You can deploy fenced configurations in three ways: „ Allow Traffic In and Out - Virtual machines can communicate with machines outside the fence and machines outside the fence can communicate with virtual machines in the fenced configuration. See Figure C‐2. Figure C-2. Allow Traffic In and Out Fencing Mode Managed Server system VM1 fenced network VR configuration network „ Allow Traffic Out - Virtual machines in a fenced configuration can initiate communication to machines outside the fence and can receive messages back on the same connection. Machines outside the fence cannot initiate communication to virtual machines in the fenced configuration. This option is useful when virtual machines need to obtain data or execute code outside the fence (as seen with Web services or databases) but do not want to receive messages that may disrupt testing.
