Socket Programming help

So I made a server and a client in C# using sockets. when i run both the client and the server on the same machine it connects. but if i run the server on my machine and the client on someone else's machine on different networks, it won't connect :/ Basically all the program does is say "Connected" if the server and client make a connection. does anyone have any ideas on how to make it work? Thanks!

2- Make sure that the server has the port which receives the connection open
3- No Firewall blocking..
4- Profit??

1- i checked the corrected IP is used.
2- "TcpListener tcplistener = new TcpListener(IPAddress.Any, 9572);" that opens the server on port 9572 and accepts any IPAddress. right?
3- How would i know?
4- As of now no but i have been thinking 'bout it so probably in the near future. why?

open cmd and type in:
IPCONFIG

Find your Default Gateway, and then paste ur gateway on the browser's url tab...
Your default gateway should be:

Code:

192.168.1.1

and the username & password: admin
Then you have to forward the port manually.

Edit:
I made a vid to forward ports sometimes ago.. It's for Modern Warfare 2, but the way is the same, you have only to change the port number...

its not necessarily your windows firewall.. but might be router one too. (and ports, don't ignore this...)
