To do this, on Windows platforms, there have been, since Windows XP, and then on Windows 7, 8, 8.1 and 10, a command line utility, not only used for this purpose, called netsh, the give the ability to expert users to redirect any incoming TCP connection (not UDP) (IPv4 or IPv6), specified on a local port to another local port or even to a remote port opened on a remote computer. Most of users have at least a Windows system available at home or at job especially at home it could be useful, usually for gaming or set up a remote internal video camera control, to be able to reach a system from a remote position or letting another system to reach us from Internet. Often, the port numbers of well-known Internet services, such as port number 80 for web services (HTTP) or 443 for HTTPS, are used in port forwarding, so that common Internet services may be implemented on hosts within private networks. When configuring port forwarding, the network administrator sets aside one port number on the gateway/router for the exclusive use of communicating with a service in the private network, located on a specific host (the internal client).Įxternal (Internet) hosts must know this port number and the address of the gateway to communicate with the network-internal service. The computers behind the router, on the other hand, are invisible to hosts on the Internet as they each communicate only with a private IP address with the router, so only this device can be "viewed" and reached by remote systems.

The NAT device's external interface (usually on a router) is configured with a public IP address. Internal network clients, on the private network (LAN), can be connected to an Ethernet switch (by using typical Ethernet cables) or communicate via a wireless LAN (Wi-Fi). This kind of configuration, in a typical home network, needs an Internet access through a DSL or cable modem connected to a router or similar. Port Forwarding is a technique that allows remote computers, usually computers or systems on the Internet, to connect to a specific system or service within a private local-area network (LAN), so an internal network.
