It might be possible, but I don't see much use of it. Anyway, you cannot just use the IP address of the existing system doing this. > > If I need to implement my own "driver" (which I suppose shouldn't be very > hard), where can I find documentation about the protocol? It's not a protocol, it's an API. It's the standard lwIP callback API for tcp connections, but the nature of the API makes it possible to hide from the application the fact that the connection is e.g. TLS in reality. Using this, it's relaively easy to convert existing tcp applications to use TLS. Regards, Simon
