What is Port Forwarding ?

Port Forwarding allows you to access a device, server or service from anywhere in the world. In simple terms, Port Forwarding will enable users to create dedicated servers, run different types of services, and much more. Port forwarding is the behind-the-scenes process of intercepting data traffic headed for a computer's IP/port combination and redirecting it to a different IP and/or port

How does Port Forwarding Work?

Data is transferred in packets over the Internet. These packets contain the details of your request, which also includes the destination of your computer or device.

Normally, a network router examines the header of an IP packet before sending it to any linked and appropriate interface. It, in turn, then sends the data to the destination that’s in the header.

But Port forwarding changes things a bit. In port forwarding, the intercepting application  reads the packet header, notes down the destination, and then rewrites the header information before sending it to another computer or server—one which is different from the computer/server you intended.

That secondary host destination may be a different server using a different IP address, a different port, or a completely different combination of the two. In the case of a VPN or proxy, this secondary destination are usually the servers employed by the provider which mask or cover your original IP address
