You can do so by opening a port on your router and assigning it to a specific device. The remaining can be assigned to any device or program you want. About the first 1,000 are ordinarily dedicated to standard specific functions. It does this automatically, but if you want your home devices to connect to a remote device, you need to set up port forwarding. Your NAT firewall, which lives on your router, sends incoming connections to the devices that requested them, by extension also blocking unwanted incoming data.


You can think of it as a mix between a security guard and a mail sorter.

To understand port forwarding you first need to understand what your router does.
