In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.

This technique is most commonly used to make services on a host residing on a protected or masqueraded (internal) network available to hosts on the opposite side of the gateway (external network), by remapping the destination IP address and port number of the communication to an internal host.

A router is a networking device that forwards data packets between computer networks.

Routers perform the traffic directing functions on the Internet.

A data packet is typically forwarded from one router to another router through the networks that constitute the internetwork until it reaches its destination node.

In computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules.

A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed not to be secure or trusted.

Firewalls are often categorized as either network firewalls or host-based firewalls.

Network firewalls filter traffic between two or more networks; they are either software appliances running on general purpose hardware, or hardware-based firewall computer appliances.

Host-based firewalls provide a layer of software on one host that controls network traffic in and out of that single machine.

Firewall appliances may also offer other functionality to the internal network they protect, such as acting as a DHCP or VPN server for that network.

An Internet service provider (ISP) is an organization that provides services for accessing and using the Internet.

Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned.

In the internet protocol suite, a port is an endpoint of communication in an operating system.

While the term is also used for female connectors on hardware devices (see computer port), in software it is a logical construct that identifies a specific process or a type of network service.
