You, you don't have to. "Fixing the problem" in this case just means signing a few agreements with Microsoft and having our driver "approved". Perhaps, not immediately but with the next Windows update.
I've tried the driver from the Host Options Drivers tab of my existing 18.104.22.168 installation but that still fails.
How exactly does it fail? Do you receive an error message?
I am sorry to hear that. However, please note that we have implemented a lot of improvements to connection speed and stability in the upcoming version 6.9. This version is going to be released by the end of May.
Indeed currently one can connect through your server if they know IP/DNS and port number. However, at some point in the future we are going implement some sort of authentication. Not to be confused with authentication already in place called custom server security - that one is used for a different purpose.
