How can I port forward my router?

So I'm trying to make a Minecraft server for some friends and I try to port forward but I don't think it's working.

I have a Technicolour Turqoise and I added this to the WAN services but when I go onto https://www.yougetsignal.com/tools/open-ports/

it says my ports are closed

is there something i'm doing that's obviously wrong?
