What to do next
You can continue configuring network settings by adding additional network components and by selecting
settings in the Network tab of a vSphere machine component in the design canvas.
Creating and Using NAT Rules
You can add NAT rules to a one-to-many NAT network component in a blueprint when the NAT network
component is associated to a non-clustered vSphere machine component or an on-demand NSX load
balancer component.
You can define NAT rules for any NSX-supported protocol. You can map a port or a port range from the
external IP address of an Edge to a private IP address in the NAT network component.
n
vSphere Machine Component
You can create NAT rules for a NAT one-to many network component that is associated to a non-
clustered vSphere machine component.
For example, if two machines are associated to a NAT one-to-many network component on the
blueprint, you can define a NAT rule that allows port 443 on the external IP to connect to the
machines through port 80 on the NAT network using TCP protocol.
n
NSX Load Balancer Component
You can create NAT rules for a NAT one-to many network component that is associated to the VIP
network of an NSX load balancer component.
For example, if the NAT network component is associated to a load balancer component that is load
balancing three machines, you can define a NAT rule that allows port 90 on the external IP to connect
to the load balancer VIP through port 80 on the NAT network using UDP protocol.
You can create any number of NAT rules and you can control the order in which the rules are processed.
The following elements are not supported for NAT rules:
n
NICs that are not in the current network
n
NICs that are configured to get IP addresses by using DHCP
n
Machine clusters
To add NAT rules to a NAT network component in a blueprint, see Add an On-Demand NAT or On-
Demand Routed Network Component.
For related information about using NAT rules, see public articles such as this vmwarelab blog post.
Add an On-Demand NAT or On-Demand Routed Network Component
You can add an NSX on-demand NAT network component or NSX on-demand routed network component
to the design canvas in preparation for associating their settings to one or more vSphere machine
components in the blueprint.
When you associate an existing network component or an on-demand network component with a
machine component, the NIC information is stored with the machine component. The network profile
information that you specify is stored with the network component.
