[How can I open ports? :(]

Got it to work. It is indeed not so hard, advice to all readers. Find a router checker and open port checker.
So I spend the last hours or half a day playing rct2 online multiplayer. It Is. Amazing.

[How can I open ports? :(]

Trying this for 2 hours now, I can't get it to work

How do I open ports??

I logged into localhost (enter ip in webbrowser) and went to portforwarding (virtual server) and there I used I think the right things,
I did port check and they were closed , anybody has any idea on how to get this to work??

I even did the firewall thing I think. Any information even if double, will do.

See images.
