FW-Rules for openVPN neccessary?

[cfusco]

I quote my own howto openvpn guide for mobile devices:

@cfusco

There is no mechanism for OpenVPN connect to communicate to any other App the use of a proxy server. For this you need to input the information in the WiFi or APN configuration file. You can find many tutorials online to accomplish this task. This is not true for iOS, which can be easily configured to relay this information to other apps, as we shall see in the next section.

In other words, in android you have to MANUALLY set the proxy configuration in the wifi and apn settings, and possibly even in some app. This works instead automatically in iOS devices.
