Sometimes you need more than a bastion for reaching your cloud resources. Bastions are great for SSH and RDP tunneling but really more limited to admins and administration. Of course site to site can be solved with OCI CPE and tunnels between colo/client networks.

There are several options for VPN servers and I use LibreSwan for testing site to site OCI tenancy VPN tunnels. LibreSwan could also work in a case of many users needing access to cloud resources but it is not easy to administer users etc.

So this time I tried a product called pritunl ( )

You should be able to use normal OpenVPN and I think even IPsec clients to connect. Pritunl also provide clients but ideally you should just be able to use anything generic.

Admin can easily add users and send an import file which includes your cert etc.. For me this worked well under Linux just using the generic network manager openvpn plugin but I need to verify Windows and Macs also.
