VCM is located in the vApp with the virtual machines that it is managing.
n
The vApp has a direct connection to the org network.
n
The vApp has a direct connection to the external network.
n
The vApp has a one-to-one IP address NAT connection to the organization network with direct
connection to the external network.
n
The vApp has a one-to-one IP address NAT connection to the organization network with a one one-to-
one IP address NAT connection to the external network.
n
The vApp has a direct connection to the organization network with one IP address to one IP address
NAT connection to the external network.
VCM does not support one to many IP addresses NAT mapping for vCloud Director vApp virtual
machines.
To determine the connection string to use when discovering the vCloud Director virtual machines, you
must know where VCM is located in the network and how NAT is implemented.

Table 3–1. Determining the Connection String Based on Network Configuration
After you collect the vCloud Director data, you can view the internal and external IP addresses in network
information for the virtual machines.
Best Practice
VCM cannot use DCOM to communicate with vCloud Director vApp virtual machines across NAT
mapped networks.
