All our appliances are designed as headless servers (headless meaning no screen/keyboard/etc). It is designed to be configured via commandline. I know that can seem intimidating if you haven't used the commandline before but it's not that bad, honest (actually it's really powerful once you get used to it).

The OpenVPN appliance includes some helper scripts to make life easy when you configure it from scratch. It also has quite good documentation.

I have set it up locally (for testing) but haven't actually used it that much. I suggest that you have a go getting it working from the docs and if you get stuck, post back and I'll try to help you out.

The 2 main scenarios that the OpenVPN appliance should support OOTB are "Gateway" and "Site-to-site".

Gateway is where you have the appliance running on the internet (e.g. Amazon). You then connect to the internet via a VPN tunnel through the appliance. You would use that if you use insecure wifi and want to ensure you are using a secure channel. It's more-or-less what you get when you purchase a VPN for web browsing (to get around geo-blocking for example). The only difference is that you are using your own server.

Site-to-site is when you want to access a remote LAN securely, or link 2 LANs across the internet. E.g. access your work's LAN when you are out on the road.

I can't be sure, but it seems that you are hoping to use it as a "Gateway". And if you follow the docs it explains how to create the client profiles. And then how to how to transfer the client profiles. You then load that info into whatever VPN client you are using. Maarten has suggested some above.
