(**) For access via the Internet, your in-house network must have a public IPv4 address (dynamic or static). There are now some internet providers who only offer a so-called Dual-Stack Lite by default (e.g. Vodafone / Kabel Deutschland, Unitymedia). In this case your in-house network only gets public IPv6 address and no IPv4 address that would be only yours. Therefore it is not possible to easily establish a connection from the Android / Windows app to the CAN-Gateway. Experience has shown that you can ask for the network only activation of the dual stack (normal, not Lite).
