[X2Go-User] how to connect an x2go client to a server over the internet?

Hi,

I want to be able to give remote support via deskstop sharing over the 
internet. I have set up a linux computer for a friend. Now I want to be 
able to see and interact with his desktop while we are both sitting at 
our homes. Is this possible with x2go? As far as I understand I would 
need direct access to the x2go server running on my friends computer. 
How to achieve this over the internet?

Thanks,
Wolfgang
