Hmm, you just don't seem to be getting it. Based on everything we've learned so far, the problem seems to be one of policy, by Apple. If the OpenVPN client is running on the same device as the app you're trying to use, and that apps falls within Apple's policy about what is NOT allowed to use a VPN (e.g., Facetime), the Apple OS will either deny it access to the internet entirely, or else bypass that OpenVPN client and access the internet directly from the cellular provider. It's just that simple. It's NOT a technical problem. It's a policy, enforceable by Apple because it sees the OpenVPN client running on its own device. Once you're using wifi and the OpenVPN client is running on the ***router***, Apple has no way to enforce that policy; it can't see the VPN.
