How to port forward a Ubee DDW3612 router for Minecraft Server?

I need to know how to port forward my router for a minecraft server. I couldn't find my router model on Portforward.com, and when i tried similar models it did not work. I used PortChecker and it says it was not able to ping my router but my port is open.

Hold the windows key and Press r. After that type in Cmd, press enter. A command prompt should pop up. From there type in ipconfig. After that look at the ipv4 address wich most of the time should be: 192.168.1.122
Copy and then pate that to your default Internet browser. A log in screen should pop up. The default user name should be admin and the password should be admin1 from there you can proceed to the routers porta and forward them to your needs.
