Hi Jorge, 

Actually, I think DDNS is probably the best solution. Apparently, the router supports that in the web interface (http://www.smallnetbuilder.com/wireless/wireless-reviews/31058-asus-rt-n16-gigabit-n-router-reviewed?start=2). Sign up for an account on DynDNS and setup the router to talk to DynDNS and then you only need to use dig or nslookup to find the public IP of your router.

Hope this helps!
