    UDP Ports

    Windows 10 appears to be a totally control-freak operating system and I'm hating it.

    I'm trying to run a TeamSpeak 3 server on my computer. It uses UDP Port 9987. I can access the port locally, through localhost or 127.0.0.1, even my internal IP... 192.168.1.116. But the instant I try to access it from the internet, it fails to connect.
    Yes, the port is forwarded in my router's port forwarding. Every program that uses TCP ports works just fine. But UDP ports are being blocked by something and I can't figure out what is blocking it. So, logically, since I don't have anything but the router,
    windows firewall and windows defender, it MUST be windows. I've checked for proxies between the internet and my router and there are none. So, again, logically, the only option left is Windows 10 itself.

    I use to be able to use UDP ports in Windows 7 and Windows 8. It stopped when I upgraded to 8.1 and then 10 it still doesn't work. Does anyone have any suggestiongs?

    I have a local portforward checking application that pings a external server that then tries to connect using the specified protocol for the specified port and it works just fine on TCP 9987, but when I tell it to check UDP 9987, it immediately comes back
    stating that a program is blocking the UDP 9987. Does anyone have any suggestions? Please, somebody help me get this working. I'm pulling my hair out here.
