I have tried to do the port forwarding but when I check to see if its open it still says close. This is what I did. On my routers page I set up port forwarding as such, the Inbound Port & Local Port to 20000 as the port of the server and IP address is set to my IPv4. In addition, I have also also set up my outbound port to 20000. I am not sure what I am doing wrong.
I got it to work. Although when I test the port it says that it is close. I can still connect to it from outside. That just throw me off. Also I didn’t you had to use your public up for it. Now it is all working.
