Connect your OCI resources to other Clouds with Libreswan

IPSec VPN view from the OCI Network Visualizer

In today’s world, the norm for videos is that they should be short in length, even if they are instructional videos. They cite the short attention span of the targeted audience…. And I do agree to some extent. However, in tech there are many occasions that  require a longer length so they can properly address all the details of the topic at hand. Back in March 2021, I recorded myself for the purpose of demonstrating how to configure to completion an Inter-Cloud VPN connection using the Oracle Cloud Infrastructure (OCI) native IPSec VPN tunnel against a Customer Premises Equipment (CPE) with LibreSwan on an Amazon Web Services (AWS) Elastic Cloud Compute (EC2) instance. The video is nearly 30 minutes long! Only the truly committed will follow along, which is the intention.  

I used official OCI documentation as a basis. Basically I explain every single step on this document while I perform them on both OCI and AWS consoles.

This is the link to this document:

Even though in the video I present myself as an Oracle employee, which I proudly am, the video and this post are NOT official Oracle documents. Any opinion is my own and only my own.

I hope that you find this step-by-step video helpful. This is the link to it:

P.S. The reason why I am using a non-RFC1918 CIDR prefix is because I am strictly following the steps in the guide.
