Hello,
I want to connect to my Yun remotely.
I think it's possible to do it by the SSH tunneling but I don't know how to do it.
Do you have some ideas?
It is possible of course. If you haven't configured your YUN, it must be acting as an access point. therefore you have to connect your computer to the wireless network of your yun.
Then just ssh root@(IP of your yun here)

You are missing one important word "reverse"
I know the "ssh root@(ip address of my Yun)" command. This command works if my laptop and my Yun are on the same local area network.
My case is:
My Yun is connected to the internet thanks to Router 1 in Paris, for example and I am connected to the internet with Router 2 in London, for example.
The devices provide two differents external IP address.
What I want to do is to connect my laptop to my Yun with PuTTY software even if they are not on the same local area network.
Do you have some ideas?
Yes, you are right Sonnyyu.
"Reverse" is the main word.
Thanks you 
I have not also the access to the administration of the router 1 in order to set a port forwarding for my Yun.
You can use the Yaler service. It gives a url to access your yun either through web or ssh. You don't need to make any changes on your router.
Thank you so much samir_sogay
