Create and configure a third-party IPAM endpoint. See Create a Third-Party IPAM Provider Endpoint.
Procedure
1 Select Infrastructure > Reservations > Network Profiles.
2 Click New and select NAT from the drop-down menu.
3 Enter a name and, optionally, a description.
4 If you have configured one or more third-party IPAM provider endpoints, select a third-party IPAM
endpoint in the IPAM endpoint drop-down menu.
When you select a third-party IPAM provider endpoint that you have registered in
vRealize Orchestrator, IP addresses are obtained from the specified IPAM service provider. IP
specifications such as subnet mask and DNS/WINS options are not available because their functions
are controlled by the selected third-party IPAM endpoint.
5 Select an existing external network profile from the External Network Profile drop-down menu.
Only external network profiles that are configured to use the specified IPAM endpoint are listed and
available to select.
6 Select a one-to-one or one-to-many network address translation type from the NAT type drop-down
menu.
Option Description
One-to-One Assign an external static IP address to each network adapter. Every machine can
access the external network and is accessible from the external network.
All external IP addresses that are assigned to an NSX edge uplink must be part of
the same subnet. When using NAT 1:1 in vRealize Automation, the corresponding
external network profile must contain only IP ranges that exist within a single
subnet.
One-to-Many One external IP address is shared among all machines on the network. An
internal machine can use only static IP addresses. Every machine can access the
external network, but no machine is accessible from the external network.
DHCP is not supported when using NAT with a third-party IPAM provider.
The NAT one-to-many translation type allows you to define NAT rules when you
add a NAT network component to a blueprint.
7 Enter an IP subnet mask in the Subnet mask text box.
The subnet mask specifies the size of the entire routable address space that you want to define for
your network profile.
For example, enter 255.255.0.0.
