The FlashRouters Privacy App features a Global Kill Switch checkbox. When checked, your FlashRouter’s Internet connection will be disconnect if the VPN connection is dropped. This will ensure that no Internet data passes through the FlashRouter that is not encrypted by VPN.
If this setting is unchecked your Internet connection will resume in the event of a VPN connection drop.
Keep in mind that this setting should be unchecked if you are using the by device Kill Switch setting on the Options tab of the FlashRouters Privacy App.
