Windows Application Comunication Over Internet

Hi, I developed a small windows application. Now I'm trying to make that running on diferent computers and out of my Local Network, I can transfer data from one aplication to another, something like returning a dataset with data from the other computer.

I already make it work in my local network, I have comunication, buut, when I try with a machine out of my network I have no luck. I know Local Network is very different than internet, because of dynamic IP's and security. But is there a chance I can extend what I achieved in my local NEtwork to the internet???

Thanks

If you're using sockets as your method of transport it should work fine over the net if it works ok on your LAN.

You must bear in mind your machine must be visible to the net (i.e. not behind a firewall) and preferably have a registered and static IP address.

and Darwen, I would add that simple routing through switches can also work as perfect as having static IP and internet exposure.
