While most functions are handled automatically by modern routers, some applications require you to forward a port to that application or computer manually. Fortunately, if you know where to look, it's straightforward.
Some video games and programs require specific ports on your router to function correctly. Although the router has some ports open by default, most of them are locked and can only be used if they are manually opened.
If your online video games, file server, or other networking programs aren't running, log into your router and open the ports that the application needs.
If you're new to networking, there are a few things you should know before diving into the topic of port forwarding. We'll take it easy.
We've covered several projects that use your computer as a server for other devices. Most stuff will work fine once you're within your network. However, if you want to use any software outside of your network, things get more complicated. Let's start with why this is the case.
Information on the Internet passes through ports, which are virtual pathways. There are 65,536 ports available. Ports are similar to extensions on a phone system, which is an excellent comparison.
Any internet-connected program on your computer is set up to transfer packets through unique ports. The ports are often chosen randomly by the software's programmers, but other times, depending on the software's features, programmers will choose a more common port.
Here are a few examples of how different ports are used in the industry:
Let's take a closer look at Port Forward a Router now that you know the basics.
Some routers have a port forwarding setup wizard that simplifies the process. For example, the router might show you a list of devices that already have a static IP address before allowing you to select the protocol and port number.
Conclusion
Hopefully, this has helped clear up some of the confusion around port forwarding and still confused? Re-read the details from above a couple more times. If you'd instead not manually configure your forwards, you can do so with just one press.
