Java sockets, how to connect Client to a Server using stream sockets with no public IP. I tried to connect using two computers connected to different providers with no public IP but I failed. How messenger programs (like yahoo messenger) can do that even with no public IP. I assigned to the Server a port no, and then activated the client to call that port with the Server IP. It is not successful. Any one can assist me in that.
Thanks in advance
Regards
