Yeah, i got the same problem, i tried using it for a minecraft server, but it didnt work, as far as i know, this is what you gotta do:

1. Download Simple port fowarding here: www.simpleportforwarding.com/download

2. Install it , an run it

3. add a port

4. Choose "Custom", or something like that

5. Choose your options

6.Click Update Router

7. Enter your password and user, you can look for it in the internet, or just click show password on the main window

8.Your port is now open! (I think)

9. Test it in the link above  :)
