[PDF] Parallels Server 5 Bare Metal

Managing Parallels Server Bare Metal Network
In this figure, the private network also includes two private subnets—Subnet 1 and Subnet 2, but
the virtual machines and Containers included in these subnets reside on two physical servers.
Container 101 and VM1 are joined to Subnet 1, and Container 102, Container 203, and VM2 are
joined to Subnet 2. The virtual machine and Container on Subnet 1 can connect to each other but
cannot access the virtual machines and Containers on Subnet 2, and vice versa.
Weak Private Networks
By default, when you create a private network, no virtual machine or Container on this network can
access
• virtual machines and Containers that are joined to other subnets in the private network
• virtual machines and Containers that are not part of the private network
• computers that are located on external networks
However, you can configure a private network so that its virtual machines and Containers cannot
communicate with virtual machines and Containers on other subnets in the private network, but
can connect to virtual machines and Containers outside the private network and to computers on
external networks. Such private networks are called weak private networks. "Weak" in this context
means that these networks can be accessed by computers on external networks and are,
therefore, more prone to security vulnerabilities and threats. The following picture demonstrates a
system with a weak private network:
