I am also a newbe, just do the first steps.
As far as I see, you can only open a http/https, RDP or VNC link.
When you setup a connection you have to choos the protocoll first and than you generate the link.
Click the link, or copy the link to the clip board and past it into some browser.
I jus wondering, why FTP protocoll is missing or why there isn#t a chance to have full network access throgh a VPN tunnel ...
With best regards
