Port forwarding is a technology that allows network traffic to come into the network on a certain port and go to a destination server with a different port. In simple terms, it is a way of forwarding incoming network traffic from one port to another, allowing a device to access a service or application running on another device on the same network.
For example, suppose you have a web server running on port 80 on a computer on your local network. If you want to access that web server from outside your network, you would need to forward incoming traffic from your router's external IP address and port 80 to the internal IP address and port 80 of the computer running the web server.
Port forwarding is commonly used for remote access to devices on a network, such as accessing a home security camera or accessing a remote desktop session. It can also be used to host servers for online gaming, file sharing, or web hosting.
To set up port forwarding, you need to configure your router or firewall to forward incoming traffic on a specific port to a device on your network. This typically involves logging into your router's administrative interface and creating a port forwarding rule that maps the external IP address and port to the internal IP address and port of the device you want to access.
In conclusion, port forwarding is a technology that allows network traffic to come into the network on a certain port and go to a destination server with a different port. It is commonly used for remote access to devices on a network and hosting servers for various applications.
