Hello, I allow myself to publish because I can not find any solution to my problem.
I have installed Owncloud to help him from Virtualbox with the Univention-App-owncloud-virtualbox. I do not touch anything even the IP which is like 192.168.1.XX
Then I manage to connect locally to this IP address.
Now my problem is that I can’t connect anywhere other than Local. If she that one would have a solution I would gladly accept it.
thank you so much
