I made a small chat client and chat server program. As we've got here a firewall, I sent the server part to my friend, who sent back his IP, and that way I could establish the connection with his computer. Of course, the client was running on my machine, as he cannot get through our firewall.
But, I tried the same thing with my girlfriend, and it didn't work.
She's got a firewall, too. And I made the whole program to be able to chat with her, when we're at the office.
Hope somebody has a really revolutionary idea, how to connect a remote, when both computers are behind a firewall?
Thanks in advance.
Have a nice code!
