Can't get port forwarding to work

[ToucaNNN]

Hello, a few days ago i decided to make a server for CS:GO and i want to host it myself. Everything went fine until i got to the port forwarding part. I own a technicolor TC7200-U. I set up the port forwarding, but when i check the ports they show up as closed ( i am using a port checking program, not a site).
I don't know what to do anymore, i checked the firewall and its turned off (there is an 'ipv6' firewall which is on), i turned 'WAN blocking' off. I set up an static ip.

Any ideas what to do?

IS the server running and open for connections when you use the test program?

Yes it is. Also i’ve seen on other posts that the wan ip should not be private( like 192.168.x.x), the thing is i can't find any 'wan ip' when i log in on the router. It has 2 sections ‘internet’ and ‘local network’. Under ‘internet’ there is only an ipv6 address, no wan ip. Maybe thats the problem?
