NSX Cloud supports enabling NAT on NSX-managed VMs.

You can enable North-South traffic on VMs in NSX-managed VMs using public cloud tags.

On the NSX-managed VM for which you want to enable NAT, apply the following tag:
Table 1.
Key Value
nsx.publicip public IP address from your public cloud, for example,
Note: The public IP address you provide here must be free to use and must not be assigned to any VM, even the workload VM you want to enable NAT for. If you assign a public IP address that was previously associated with any other instance or private IP address, NAT does not work. In that case, unassign the public IP address.

After this tag is applied, the workload VM can access internet traffic.
