Port Forwarding

Port Forwarding is the method of forwarding traffic from the network port of one computer to another. A port in this case is not a physical connection point but rather a virtual network connection associated with a specific protocol or service. For example, the port for http web services is port 80 and the port for DNS services is port 53. You can configure Port Forwarding on the IT-100 to allow a user or service on the Internet to connect to a different port on a computer inside your private network. When you create a Port Forwarding rule on the IT-100, you are opening that port on the device and allowing only a specific type of traffic to connect to a port on either a particular machine or the entire internal network.
