Let’s IPSec VPN – How to connect your Unifi Security Gateway to Oracle Cloud Infrastructure

When I connect from home to the Oracle Cloud Infrastructure normally I used a Bastion Host, an Open VPN compute instance or Public IPs.  Some of the cool stuff like MV2OCI (which transfers data from on-premises to OCI) or integration of an ADB instance in my local running Oracle Enterprise Manager are referred to direct cloud connections.

Jump! In our Trivadis Oracle Cloud Infrastructure training environments, we never use direct access to an application or database server by a public IP address. For this case, we use an Oracle Linux based bastion host which acts as a jump host. For security reasons, I never put any SSH keys on a bastion host to connect from there to the target instances. If your bastion host is compromitted, your SSH keys are lost! In one of the last trainings,…
