What are Virtual Services and Port Mapping?
The DI-701 works by blocking ports. However, when you are contacting servers on the Internet that you want to communicate with, these ports become unblocked dynamically to allow incoming response traffic. If you are running a web server, ftp server, game server, or VPN server you may wish to unblock these ports permanently so that incoming traffic can always reach a machine behind the DI-701. This will ensure that users will be able to access your machines locally over the Internet. This is known as setting up Virtual Services or Port Mapping. It will route any incoming traffic to a specific port to one specific machine behind the DI-701. The port number and local IP address for the local machine must be specified. Once this is configured, any incoming traffic on that specific port will be routed to the specified machine.
