VPN Connect Quickstart

Using the VPN Connect workflow is the quickest way to set up an IPSec VPN between your on-premises network and your A virtual version of a traditional network—including CIDRs, subnets, route tables, and gateways—on which your instance runs.. The workflow is a guided, step-by-step process in the Console that sets up the IPSec VPN plus related Networking service components.

Purpose of the Workflow

VPN Connect involves setting up and configuring several Networking service components. The purpose of the workflow is to set up those components for you. In general, the workflow does the following:

  • Uses a template with assumptions that will help you get started.
  • Asks you for some basic network information.
  • Sets up the Networking service components for you.

The workflow is a task within the overall process of setting up VPN Connect, which is illustrated in the following diagram. The workflow is the shaded box.

This image shows a flow diagram of the overall VPN Connect setup process.

Notice that the overall process includes work by a network engineer in your organization. That engineer provides information that you, in turn, must supply during the workflow. The workflow returns information that the network engineer needs when configuring your CPE device.

The following short sections summarize each task.

Task 1: Information to get from your network engineer
Task 2: Workflow
Task 3: Information to give to your network engineer
Task 4: CPE configuration
Task 5: Testing

Workflow Assumptions

  • Static routing only: Although VPN Connect supports either BGP or static routing, the workflow only lets you set up static routing for your IPSec tunnels. If you want, you can later manually switch them to use BGP.
  • You do not already have a VCN: The workflow automatically creates a VCN for you, along with related resources. If you instead have an existing VCN that you want to set up VPN Connect for, you can follow the step-by-step instructions in Setting Up VPN Connect.
  • You want an internet gateway for easy initial access to the VCN: The workflow automatically adds an internet gateway to make it easy for you to quickly create an instance in the VCN and connect to it over the internet. You can delete this internet gateway later if you don't want it.

Alternative to the Workflow

If the workflow does not meet your specific needs (for example, if you already have a VCN or want to use BGP for routing), you can manually set up VPN Connect yourself. For step-by-step instructions, see Setting Up VPN Connect.

What the Workflow Creates for You

The workflow assumes that you start with only on-premises network and a CPE device. The workflow creates the numbered components in the diagram for you. The table describes each component.

This image shows the Networking service components that are created for you.

Number Component Description Can Use Existing One or Create New One?
1 CPE A CPE is a virtual representation of your actual CPE device. This virtual representation contains basic information such as the CPE device's public IP address. Yes, you can either use an existing CPE or the workflow creates a new one.
2 Dynamic routing gateway (DRG) A DRG is a virtual representation of the actual router at the Oracle end of your VPN Connect. Yes. If you use an existing one, it must not already be attached to a VCN.
3 VCN A VCN is the extension of your on-premises network into the cloud. You can later add Compute instances and other cloud resources to your VCN. No. The workflow automatically creates a new VCN.
4 Subnet A subnet is a subdivision within the VCN. The workflow creates a regional A subnet in which instances are allowed to have public IP addresses. When you launch an instance in a public subnet, you specify whether the instance should have a public IP address.. You can later add more subnets later if you like. No. The workflow automatically creates the subnet in the new VCN.
5 Internet gateway An internet gateway is a virtual representation of the actual router that gives your VCN access to the internet. Although this gateway is not necessary for VPN Connect, the workflow creates it to make it easy for you to quickly access any instances or other cloud resources you later create in the VCN. You can delete the internet gateway later if you like. No. The workflow automatically creates an internet gateway for the new VCN.
6 Default route table with rules

The VCN automatically comes with a default route table. The workflow configures the subnet to use this route table and adds two types of rules:

  • One or more rules to route the desired VCN traffic to your on-premises network by way of the DRG. There's one rule per on-premises network route that you provide in the workflow.
  • One rule to route the remaining VCN traffic to the internet by way of the internet gateway.

You can edit the rules or add more later if you want.

No. The new VCN automatically comes with this component.
7 Default security list with rules The VCN automatically comes with a default security list. The workflow configures the subnet to use this security list, which automatically comes with default rules to enable basic traffic flow. The workflow also adds one or more rules to allow all types of traffic from your on-premises network. There's one rule per on-premises network route that you provide in the workflow. Notice that the security list does not include rules to allow ping. No. The new VCN automatically comes with this component.
8 VPN Connect IPSec tunnels The workflow creates two IPSec tunnels, each with specific configuration information that you must provide to your network engineer. No. The workflow automatically creates the tunnels.

Where to Access the Workflow

  1. In the Console, click the Oracle Cloud icon at the top of the page to go to the Console home page.

    The page has a Quick Actions section to take you directly to common tasks.

  2. Click the quick action for Networking Solutions: Create an IPSec VPN connection.

    The workflow starts.
