You need to use User Defined rather than the built in, so it'd be up to you to ensure the ovpn files you're using are correct/current and put everything in the User Defined directory.
I think it tells you everything you need to know, but come back with questions if not.
Yup, works a treat. I set it up manually and was able to validate each connection separately and have them all appear,
One of the things that was confusing me was the fact that you can't organize different VPN connections by subdirectory under UserDefined. VPN Manager won't see them, either via the wizard nor if manually set up. The Wiki does sort of mention that, although it says that you can upload a directory full of files, which could be interpreted to imply that you could put a subdirectory under UserDefined. It might be more clear to indicate that all VPN-related files must reside within UserDefined for those of us who are a bit denser...
I could go so far as to say that it might be nice if subdirectories were supported, allowing each connection to be organized within its own folder like the preset connections are (is there an editable list of those preset folders somewhere that you could add your own presets to, either within the code or within the supporting files?), which would eliminate the need for a separate name for each key and certificate file, but it works fine the way it is (if you RTFM) so I'd once again like to express my gratitude for such a handy addon. I like to turn my brain off when I turn the TV on, and being able to have different VPN connections automatically activated for different addons is a wonderful thing, with no ssh sessions required, and that's before you even mention important matters like Wife Acceptance Factor.
