I have opened a port , for example with the firewall program , through my server, without opening a port in the router, through my server with the program “mouse.exe” and opening a port , for example 1313. By calling through the internet, you can search for “mouse.exe” and then maybe you can access my server or talk to the server even. I’ll let you know the connection is not available, but you can try and it’s a port through the firewall. The person can talk to me or my server through the port ? Think it’s possible?
