Connecting an SDDC to the Internet

Learn how to connect your SDDC to the internet through a NAT gateway.

The workflow for configuring connectivity between your SDDC and the internet through a NAT gateway does the following:

  • Determines whether the VCN has a NAT gateway, and if not, helps you create one.
  • Adds a default route rule to the SDDC's NSX Edge Uplink1 VLAN's route table to send traffic to the internet through the NAT gateway.

To use Oracle Cloud Infrastructure, you must be granted security access in a policy  by an administrator. This access is required whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you get a message that you don’t have permission or are unauthorized, verify with your administrator what type of access you have and which compartment  to work in.

Note

The workflow adds a required route rule to the VLAN's route table. If you have reached your route rule limits, you are prompted to check your existing rules and delete one to free up capacity.

Using the Console

  1. On the Details page of the SDDC, click Configure connectivity to the internet through NAT gateway.
  2. Review the details of the planned updates to your networking resources.

    If you choose to disallow an update, your SDDC might not have internet connectivity through the NAT gateway. To complete the configuration, you can either return to the workflow later or make the required resource update manually outside of the workflow.

    If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you're not sure whether to apply tags, skip this option or ask an administrator. You can apply tags later. To see the tagging options, click Show Advanced Options. The tags you specify are applied to all of the new resources created in this workflow.

  3. When you are satisfied with the configuration settings, click Apply Configuration.

    The Console displays the status of each operation in the workflow. In an error occurs, you can retry the operation. When you close the Applying Configuration window, you return to the SDDC Details page, which shows a summary of the resources that were updated and allows you to view each one by clicking the applicable link.
