Multiple simultaneous tunnels.

Tom.Richardson

I found the following article on the OpenVPN forum:
https://forums.openvpn.net/viewtopic.php?t=22036
But it talks about using TAP interfaces, which the Android API does not support:
https://openvpn.net/faq/why-does-the-app-not-support-tap-style-tunnels/

So does the first article apply to the Android version of OpenVPN Connect?
ie. Is it possible to create multiple tunnels simultaneously with Android OpenVPN Connect?
If so, how?

Hello Tom.Richardson,

On Windows, macOS, and Linux, it is possible to have multiple VPN TAP adapters and multiple connections can work there. Even so OpenVPN Connect will not do it because it is designed to allow only one connection on purpose (to avoid people inadvertently creating insecure or broken situations when doing multiple connections to different VPN servers that give conflicting routing instructions). On Android and iOS it is not possible to have more than one connection due to the limitation in its VPN API to have only one VPN connection active.

To use multiple connection on Windows, macOS, or Linux though, you'd need to use an alternative client like OpenVPN GUI or TunXTen or Viscosity or Tunnelblick or something of the likes, or the standard OpenVPN2 or OpenVPN3 Linux client for Linux which already supports this out-of-the-box.

So no, it is not possible to have multiple connections with Android OpenVPN Connect, for 2 reasons. OpenVPN Connect is designed for one connection and the VPN API on Android only allows one connection.

Kind regards,
Johan
