2 Add one or more IP blocks, or IPAM provider ranges, by using the provider-specific search syntax or
selecting from the Search drop-down menu.
The IP blocks are retrieved from the third-party IPAM provider.
Selecting a network range may result in an empty list when using a third-party IPAM provider. For
details, see Knowledge Base article 2148656 at http://kb.vmware.com/kb/2148656.

Creating a NAT Network Profile For an On-Demand Network
You can create an on-demand NAT network profile that uses either the supplied vRealize Automation
IPAM endpoint or a properly configured and registered third-party IPAM endpoint.
Create a NAT Network Profile By Using the Supplied IPAM Endpoint
You can create an on-demand NSX NAT network profile relative to an external network profile. When
using the supplied vRealize Automation IPAM endpoint, you can assign ranges of static IP and DHCP
addresses to the NAT network profile.
NAT networks use one set of IP addresses for external communication and another set of IP addresses
for internal communication. External IP addresses are allocated from an external network profile and
internal NAT IP addresses are defined by a NAT network profile. When you provision a new NAT network,
a new instance of the NAT network profile is created and used to allocate machine IP addresses.
You can use IP ranges obtained from the supplied VMware IPAM endpoint or from a third-party IPAM
service provider endpoint that you have registered and configured in vRealize Orchestrator, such as
Infoblox IPAM. An IP range is created from an IP block during allocation.
For a NAT one-to-many network, you can define NAT rules that can be configured when you add a NAT
network component to the blueprint and can be changed when you edit the NAT network in a deployment.
Procedure
1 Specify NAT Network Profile Information with the vRealize Automation IPAM Endpoint
The network profile identifies the NAT network properties, underlying external network profile, NAT
type, and other values used to provision the network by using the embedded vRealize Automation
IPAM.
2 Configure NAT Network Profile IP Ranges with the vRealize Automation IPAM Endpoint
You can define one or more ranges of static IP addresses for use in provisioning a network.
