For example, an application on your computer will have an IP address with a port number attached like 192.168.0.2:80 or 10.0.0.2:80. Then, on top of that, the applications and services on each device are also assigned a port number. For example, your computer will have a private IP address like 192.168.0.2 or 10.0.2. To do this, your router assigns each device in your LAN its own local IP address. Your router’s job is to transmit an internet signal to all your devices over a local area network (LAN). In order to understand port forwarding, it helps to understand a little about how routers work first. By setting a specific port for your devices, you are telling your router to always accept requests for those ports and forward data to a device’s private IP address. Port forwarding is a way of making your router use a specific port to communicate with certain devices. Here’s how to forward ports on your router using a Mac or Windows 10 PC.
