Networking and Internet technologies are developing at a tremendous pace. Today, there is a large number of completely free software that allows even a non-professional to create and administer network services for a wide variety of purposes. So, you can install your own FTP or HTTP server, DC ++ exchange hub, and online game server on your home computer. However, in order for users on the external network to be able to access these services, you must open the external port on which these services accept connections. This is done by changing the firewall settings.
