Curious why your changing ports in your forward from 3395 to 3389? You sure you actually told your rdp client to connect to port 3395?

And also if still having issues - post up screens of your rules so we can see what your doing wrong.. Have source port set is common mistake.
You sure its not just local firewall of where your trying to rdp too - this is another common mistake. Your off that boxes local lan, so its firewall most likely is not going to have that open. Unless you set it to be.
