After log in, click on the hamburger icon on the top left. Then select "Compute" -> "Instances".


Click on the "Create Instance" button.


In the subsequent screen, name the virtual machine, select an image (recommend: Ubuntu 16.04), select a shape (select a always free one if needed), upload your ssh public key. Then click the "Create" button to create the VM.


In the next page, wait until you see the public IP of the virtual machine.


Open necessary network ports

Click on the hamburger icon on the top left. Then select "Networking" -> "Virtual Cloud Networks".


Click on the Victual Cloud Networks (VCN) entry in the table. The name of your VCN may be different from what you see here.


In the subsequent screen, select "Security List" under the Resource section. Then click on the Default Security List that you see.



In the next screen, click on "Add Ingress Rules".


Use the pop-up window to create the following ingress rules.



The virtual machine is now ready for OpenVPN install.
