OpenVPN is very simple after the December update. Prior to that, it was more tricky.
Download the Brian Hornsby VPN add-on, and that’s it. If you encounter any problems, please start a forum post and let us know what’s not working so we can help.
The next update should also allow you to use the Nederland add-on as well, assuming that the problem was related to how Vero 4K reports its machine architecture.
You haven’t provided a debug log however, so this is a complete stab in the dark. If you do so, I am confident we can get this to work for you very promptly.
Please help us help you.
