Setting Up Port 10308 Forwarding for Flight Simulator on Technicolor CGA2121 Router

Hello,
Wanting to set up a server in a certain flight simulator, I read that I need to have port 10308 redirected. So in the router settings (technicolor CGA2121 from Inea, I set port forwarding, UPNP to enabled and DHCP IP reservation of my computer. I am sending screenshots of settings in the attachments. I have my IP set to public, because I contacted Inea Unfortunately when I go to any port checking website it informs me that the port is closed for my IP I have no idea what I am doing wrong.

Disable that crappy UPNP as it may be confusing you.
Your redirection is set up correctly.
If that doesn't help, try setting the DMZ to your computer's address for the test.
There is still a firewall to check.

UPNP disabled, DMZ also set to the IP address of the computer and unfortunately still the same. Every time I change, I reset the router to be sure.
As for the firewall, I send the settings in the attachment.

But you know that for the port to work, you have to run what this port uses - that is, first you run the simulator and then check the port.

Here you have the instructions, it explains what, where and how to redirect:
