Is it possible to access Arduino Yun outside my local network?

I just purchased a Yun (lots of fun) and I've been successful setting up the Bridge network and reading/writing to pins, but only within my local network. Is it possible to access the Yun outside my network?

Yes, if you change the settings in your router and pass a certain IP number on to your local device.
Your network will become less secure when you set a port open in the router.

same here, I can't make bridge commands works with my public IP.

My old Uno + Ethernet shield works just fine using port forwarding. I have not seen any example of the REST commands using public IP.
