Thank you! Indeed I tested it and all the ports I tested are closed... I have a router and a modem that I use. I tried to forward the port from router... but I couldn't. See here what settings I tried: http://www.coderanch.com/t/472724/So...t-working-over

I develop a chat (server and client) using Sockets. It's working on LAN but when I try to connect the client to the server using my public IP address it says it cannot connect to that address. For example: 192.168.1.66 is ok but 92.84.65.32 (public) is not, client cannot connect to this address. My address is public - a friend pinged my address successfully. You find everywhere examples and code for chat applications - but only over local network....
