Hi anonymous,
thanks for your idea - you're right, that's a possibility to encrypt the data on it's way through the internet,
but it's not a simple SSL/TLS tunnel, it's far more (complicated) than stunnel.
Take HTTP for example, put it within a SSL/TLS tunnel and you get a HTTPS connection.
That's what I need for the RS232 Data connection and that's what the server we are connecting to is expecting. On the RUT955 we use exactly this encryption with great success - and that's what I'm looking for on the TRBs.
