Socket Programming Help...

[Dudzzz]

Hi Guys, im learning how to use Sockets in C# and im in the process of making a very simple 'MSN Like' Chat application. Its coming along nicely, i've tested it and it works fine on Local Networks like my one at Uni but if i try to connect to someone over the Internet e.g. my friend located on a different network, it doesn't work, the Client is able to connect to the Server, but the messages being sent are not displayed...

I spoke to my lecturer about this and he said that i would need to set up port forwarding for both machines so that my computer knows what to do/where to send "X information" it gets on "X Port".

This is really tedious to do, especially for someone thats not so tech savvy, so is there a simple way to do this in code automatically? Sorry if it's a silly question, but im new to Network Programming... :P

I can add full code to demonstrate what im doing if neccessary... Thanks Guys

You really need to forward the port in the router. But only on the server machine and not both.

So there really isn't a workaround for this?
