To understand port forwarding, you need to know a bit about how networking works. Every device on a network has an IP address, which is a unique identifier that allows other devices to communicate with it. Devices also use ports, which are like doorways for specific types of traffic. For example, web traffic typically uses port 80, while email traffic typically uses port 25.
When a device on a private network tries to access a resource on the public internet, the traffic is usually blocked by the router because it is trying to protect the private network. However, port forwarding allows specific traffic to be forwarded from the router to a particular device on the local network, allowing external devices to access resources on the local network.
To set up port forwarding, you'll need to do the following:
Determine the IP address of the device you want to forward traffic to. This can usually be found in the device's network settings.
Determine the port number you want to forward traffic to. This will depend on the service you want to access.
Log in to your router's web interface. This can usually be done by entering the router's IP address into a web browser.
Find the port forwarding section of your router's settings. This may be called "virtual servers" or "port mapping" depending on your router.
Create a new port forwarding rule. You'll need to specify the IP address of the device you want to forward traffic to, as well as the port number you want to forward traffic to.
Save the port forwarding rule and exit the router's settings.
Once you've set up port forwarding, you should be able to access the service you want to use from an external device by using the public IP address of your router and the port number you forwarded traffic to. For example, if you forwarded port 80 to a web server at IP address 192.168.1.100, you could access the web server from an external device by entering the public IP address of your router followed by ":80" in a web browser.
In conclusion, port forwarding is a powerful networking technique that allows devices on a private network to access resources on the public internet. By following the steps outlined above, you can set up port forwarding on your router and start accessing your favourite services from anywhere in the world.
What is port forwarding?
Port forwarding is a networking technique that allows devices on a private network to access resources on the public internet by forwarding specific network traffic from the router to a particular device on the local network.
In other words, when a user tries to access a specific service or resource on a device located behind a router, port forwarding helps to redirect that traffic from the external network to the internal device that is hosting that service. This is achieved by opening a specific port on the router and redirecting the traffic that is received on that port to a particular device on the local network.
Port forwarding is commonly used to host servers, remote desktops, and other services that require external access. It is also a popular technique used by gamers to host game servers and allow other players
