First things first: It´s great that you are here and want to participate in our SNAP workshop.
It was quite a challenge to make this work but after some testing, we think the solution works and we can have people from all around the world participate in our first hybrid workshop and use our on-site hardware. We are happy to receive feedback afterward about the things that didn´t work (and of course if it worked, we are happy to hear that as well).
But here is how to connect.
We are using OpenVPN for this. OpenVPN has clients available that make it easy to set it up on any major operating system. To get the official instructions please visit the OpenVPN Connect Website.
