I have been trying to do port-forwarding on my router (Huawei E5172 4G Router). I've done this before and it worked but i can't get it to work on this router, and i have no idea why!

While I was searching for some solution i came across something about setting the DMZ to your Local host adress which is in my case 192.168.1.4:
But nothing changed.
This was an ISP issue, after contacting my ISP they informed that the service need to be added for 5.3USD, i told them to add the service and its now working. Thank for you help!
