If I understand it correctly, @Buenavista does have a Safe-T Connect, which is not working. I also have a Safe-T Connect, it’s an older product line from SYR which does not have any port open, except 80 for the configuration interface. I have already tried a lot of things but I did not find any solution.
Edit: the configuration interface does help neither, you can only change IP settings and the web interface address.
