Astrill Router Applet:Wifi Filter
You can enable VPN either for all Wifi radios or just selected ones. This gives you a greater flexibility to choose which device will route over the VPN or through direct connection by simply switching Wifi connection on them without a need to use Device Filter and reconnecting VPN everytime you make a change in Device Filter. This overrides Device Filter rules.
