Hello, can i talk to someone who is not connected to my network, like who lives about a mile away? If so, how ?
In theory - Yes. But you havent specified enough information about your setup and network to be able to advice anything.
At least you should say wether your server has only internal IP address or does it have an external one assigned to it, or does it have a resolvable DNS domain name. You will also probably need to forward some ports in your router to that internal IP (if you server is insede your internal network) and also configure your firewall to let connections through. A lot of stuff.
