[RESOLVED] TCPConnection through router

[ThomasJohnsen]

Hola all from a new member

I have written a server/client application using TCP connections. On a LAN it works just fine, since I can supply an IP-address and a port to get from client to server. The problem is that the server program is supposed to be running on a remote machine behind a router, and I can't seem to establish a connection no matter what or how I try.

In short: Computer running server application has IP A and hides behind a router with IP B. I'm using port P. Establishing a TCP connection to A:P isn't possible, due to it being a general IP supplied by the router, and using B:P will not allow me to reach the designated computer. What do I do?

Hopefully this forum can help. Thank you in advance.

#EDIT: Forgot to write that I primarily use VB.Net, but any code solving the problem using TCP would help immensely. Converting it will be little effort compared to the hours I've spent on this.
