I've tried to port forward 27015 for my csgo server both udp and tcp, also tried my teamspeak server 9987 udp. and none of them couldn't get opened. I'm using Windows 10 with the latest updates and ethernet connection from my router which is called Ubee Wifi Modem. Everything is set in my router settings such as static ip assigned to my PC. Also tried to give access through firewall, didn't work, tried turning off firewall and windows defender, still didn't work. So I called my ISP to see if they are blocking ports but they checked it and said that everything works fine. So I'm assuming that something on my Desktop is blocking the ports from being forwarded. Any idea what to do or try?
