A hardware port is what you use to physically connect devices and/or device cables to your computer or network. You can find many of them on the back of your computer or router. Each application is designated a port number (or port) to use for transferring data.
.
In this way, how does port forwarding work on a router?
Port forwarding on your router allows you to enter a port number (or possibly a range or combination of numbers, depending on the router), and an IP address. All incoming connections with a matching port number will be forwarded to the internal computer with that address.
One may also ask, does it matter which port I use on a router? Yes, that is the correct setup. You can just image the switch as an additional ports of the router. This is basically a plug-and-play unit, no need to configure anything. Feel free to ask if you have more questions.
One may also ask, what is the purpose of port forwarding?
Purpose. Port forwarding allows remote computers (for example, computers on the Internet) to connect to a specific computer or service within a private local-area network (LAN). External hosts must know this port number and the address of the gateway to communicate with the network-internal service.
What ports are open?

Why is port forwarding dangerous?
1 Answer. Forwarding ports is NOT inherently dangerous in itself and YES the safety is dependant on the service at the target port.
