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. You can change a NAT rule when you edit the NAT network in a deployment.
