Luckily, you have almost all the information you need already. For the rest, you need to know about port forwarding. NAT can handle such requests in certain circumstances. It works exactly the same in reverse! When a computer on the Internet requests, for example, a web page from your IP address, your router needs to figure out which internal device is a web server so the request can be filled. When our web server responds, your router will know exactly which device to relay that response back to. Instead, the request goes to your router, which makes a note of which internal device is requesting the information, then sends that request out to the Internet. For instance, when you click on this link to our site,, the request doesn't go straight out to the Internet. While each device in your network has its own IP address, from the outside, every request coming out of all of those devices appears to be coming from the single publicly visible IP address assigned to you by your Internet Service Provider. NAT, or Network Address Translation, is a technology that allows each device on your network to have its own IP address.
With that out of the way, we should talk about NAT.
A port can only be used by one program at a time. When one computer sends data to another computer, it sends it from a port on an IP address to a port on an IP address. Every IP address is divided up into many ports. Every device on the internet has at least one IP address. Now that you have a basic understanding of port forwarding, let's dive a bit deeper If you would prefer to set up your forwards with just one click instead of setting it all up manually, take a look at Network Utilities. If you're ready, head straight into our Router Guides which will walk you through the process of forwarding ports on your specific router. Hopefully, this has demystified port forwarding a bit.

Ports are virtual pathways on which information on the Internet travel. There are many other reasons you may need to forward a port, this is not an exhaustive list.

Don't worry, we'll take it easy!īefore we dive too far into this, we would like to answer some of the questions that you might have on a basic level.
