I've also unabled uPnP just to get it over with but even that didn't work. I've used several open port scanners but the port stays closed. So my last option was to disable the firewall entirely or atleast lower the security from high to medium/low or off but my ISP locked the firewall so I can't adjust it.
I've contacted both parties. My ISP told me that they don't have any email or telephone support for port forwarding so I had to contact ZTE. And ZTE tells me that I need to contact my provider. So I'm pretty much stuck in the middle.
If anyone has any ideas in order to open the port, turn my firewall off or anything like that please let me know.

Thanks a lot for your help man, I appreciate it a lot. I've heard about DMZ but I've never set something up like that. I'm going to google on this subject to see how I can make this happen. The reason way I totally disabled Comodo was just to test and see if that program had something to do with it, but this was not that case it seems. I hope I'll find out how to set it up DMZ. I'll get back to you as soon as possible.
I'm using a game named "Darkfall" that requires port 32500 to be open. I just checked on my other computer if it had the same issue and it did. That computer has Windows XP with only zone alarm which I disabled but the port check still said that the port was closed. I changed the DMZ IP address and also the port forward to the IP address of that computer Do you know DMZ and uPnP and/or port forwarding have interference with each other so that it blocks one another or something like that? I'm running out of options
