Actually, one could write a a tap emulator based on tun that would add layer2 information on send and strip layer2 information on receive. But this tap emulator would also have to implement ARP and possibly a DHCP client. I am not aware of anybody doing any work in this direction. Contact me if you want to start coding on this.

All data on the sdcard is inherently insecure. Every app can read it (for example this program requires no special sd card rights). The data of this application can only be read by the application itself. By using the import option for cacert/cert/key in the file dialog the data is stored in the VPN profile. The VPN profiles are only accessible by this application. (Do not forget to delete the copies on the sd card afterwards). Even though accessible only by this application the data is still unencrypted. By rooting the telephone or other exploits it may be possible to retrieve the data. Saved passwords are stored in plain text as well. For pkcs12 files it is highly recommended that you import them into the android keystore."

Please read the Connection warning FAQ before using this option. Reconnect on reboot Ignore Restart Configuration changes are applied after restarting the VPN. (Re)start the VPN now? Configuration changed Could not determine last connected profile for editing Duplicate notifications If Android is under system memory (RAM) pressure, apps and service which are not needed at the moment are removed from active memory. This terminates an ongoing VPN connection. To ensure that the connection/OpenVPN survives the service runs with higher priority. To run with higher priority the application must display a notification. The key notification icon is imposed by the system as described in the previous FAQ entry. It does not count as app notification for purpose of running with higher priority. No VPN profiles defined. Use the <img src=\"ic_menu_add\"/> icon to add a new VPN Use the <img src=\"ic_menu_archive\"/> icon to import an existing (.ovpn or .conf) profile from your sdcard. Be sure to also check out the FAQ. There is a quick start guide. Routing/Interface Configuration The Routing and interface configuration is not done via traditionell ifconfig/route command but by using the VPNService API. This results in a different routing configuration than on other OSes. The configuration only consists of the IP of the tunnel interface and the networks that should be routed over this interface. Especially no peer partner address or gateway address is needed. Special routes to reach the VPN Server (for example added when using redirect-gateway) are not needed either. The application will consequently ignore these settings when importing a configuration. The app ensures with the VPNService API that the connection to the server is not routed through the VPN tunnel. Since only specifing networks to be routed via tunnel is supported extra routes not pointing to the tunnel cannot be supported either. (e.g. route x.x.x.x y.y.y.y net_gateway). The log windows shows the current configuration of the VPNService upon establishing a connection. Do not fallback to no VPN connection when OpenVPN is reconnecting. Persistent tun OpenVPN Log Import OpenVPN configuration Battery consumption In my personal tests the main reason for high battery consumption of OpenVPN are the keepalive packets. Most OpenVPN servers have a configuration directive like \'keepalive 10 60\' which causes the client and server to exchange keepalive packets every ten seconds. While these packets are small and do not use much traffic, they keep the mobile radio network busy and increase the energy consumption. (See also <a href="http://developer.android.com/training/efficient-downloads/efficient-network-access.html#RadioStateMachine">The Radio State Machine | Android Developers</a>) This keepalive setting cannot be changed on the client. Only the system administrator of the OpenVPN can change the setting. Unfortunately using a keepalive larger than 60 seconds with UDP can cause some NAT gateways to drop the connection due to an inactivity timeout. Using TCP with a long keepalive timeout works, but tunneling TCP over TCP performs extremely poorly on connections with high packet loss. (See <a href="http://sites.inka.de/bigred/devel/tcp-tcp.html">Why TCP Over TCP Is A Bad Idea</a>) The Android Tethering feature (over WiFi, USB or Bluetooth) and the VPNService API (used by this program) do not work together.
