When Port forwarding is used, this signal is intercepted and the application rewrites the port number. Normally, a network router recognizes the port and sends the packet to the right destination. These packets contain information about the request’s final destination including a port number.
When you access a website from your computer, you send packets of data that contain information about your request over the web. Here is a quick description of how port forwarding works. Port forwarding might improve performance and internet traffic speed to a device. This method can be used to open different paths to your network. It redirects internet data assigned to one port to a different port. Port forwarding is a method that remaps ports between remote and local computing devices. Blocking a single port will block all internet traffic directed to that port. Ports are important for internet security. An example is port 21, which is conventionally assigned to data for FTP requests.
Port numbers determine distinct “roads” for internet traffic, which prevents conflicts.
