Alright, after infinite amount of trying, doing everything I know, I have come to the conclusion that I am unable to forward a port, no matter what.
The router/modem I am using is Technicolor TC7200.
The game I am trying to use port forwarding for now is Terraria, I set up the server correctly, i re-check everything over and over, I use a legit steam client, but nothing works.
I have done the port forwarding with entering my public IP adress in the external IP field as well, but same result.
I will provide some photos,
Please help me!

Try putting the device in the dmz. See if that works.
Samir thank you for the reply, I have tried that as well, it does not work.
I have added inbound and outbound rules for TCP and switched the port forwarding to TCP, still no luck.
I get a WAN IP adress beginning with "100", my public adress beginning with "92".
So I am little bit confused, is something wrong?

If your wan IP is different than your public IP, then there's a router in between somewhere and that's the problem. :(
But... how is that possible, I only use this thing, it's like a modem with a Wifi, nothing else at all, connected with my pc through an ethernet cable...
I've tried setting up a manual static WAN instead of the DHCP, but when I write a random IP, i have no internet.
Any idea what to do?
 
Part of the block of addresses that start with 100 was created a number of years ago to allow cell phone providers and other ISP to assign private IP addresses without using the more common 10.x.x.x. or 192.168.x.x.

This block of ip is private and the carrier is running NAT to map it to a public IP that you share with many other users. You would have to put port forwarding rules in the ISP router.

You have very little option. You can ask your ISP if they will give/sell you a public IP. If not your only choice is to change ISP. There are some VPN services that assign fixed public addresses but they can be a little costly.

I just called them, it's a bit expensive for a static IP, compared to my old ISP where i used to have a static IP for the same price.. Well thank you very much for the replies!
