So i port forwarded the port 25565 (minecraft) and i put the internal ip there i log in my server using my internal ip or using 127.0.0.1

anyway people cant join the server with my external ip i dont know why i ran a test and it says its filtered the way the port is sent is only by sending it and not coming back so i chose a tester that allows the option dont ping which doesnt wait for a respond from the packets sent in by it

i tried to fix this buy making my computer act as a DMZ but its still responds with filtered
is it possible that my Internet Provider blocking it ?
please help thanks :)
