问题
Guys, i implemented a Socket with Client and Server side. When I use my local IP (192.168...) it works. But when I put the Internet IP, it doesn't work! What's the main causes for that please?
Thank you

You have a firewall or NAT device between you and the internet.
You should forward your port in your router.
