Application does not connect over internet.

Hi,

I'm making a client TicTacToe application and a server TicTacToe application.
The server application is to run on my computer the it's IP according to whatismyip.com is 175.110.58.234.
On the client application, I made a socket which connects to that IP with port 8558.

I sent the client application to my brother (who lives in a different city) and asked him to connect with my server but it failed to connect.

Am i using the wrong I.P ? When I used local addresses to test locally on my computer - the client connected to the server successfully.

Thanks for your help.

Make sure you don't have a firewall preventing external access to that port, and make sure your server is running when you attempt it from a remote machine.

My Firewall was on. I turned it off but the client app was still unable to connect. Server was running at the time.

Have you tried connecting using your IP address from your computer vs using the localhost address?

[eLancaster]

Yeah I did try that but that didn't work either which is why I think I might be using the wrong ip.

but that didn't work either which is why I think I might be using the wrong ip.

So you can reproduce the problem on your own computer which is good...I presume the client is throwing an exception? Do you have a stack trace? Is it truly a timeout? How did you distribute the app (webstart, jar, applet - both webstart and applet will have to be signed for them to work)?

Yup there is an exception, but I didn't find it very helpful. It's just a connectException.

java.net.ConnectException: Connection refused: connect

The Application is a Runnable JAR.
