So, what is port forwarding? In layman’s terms, port forwarding is when you tell your router where to send traffic that is coming in on a certain port. Let’s make it simpler, without getting too technical, think of your router as a big electric fence with a few gates in it. Those gates are called ports, and by default, most of them are closed. That’s because open ports can be like an open door to your home network, and we all know that an open door is an invitation for burglars.
When you want to do something like run a mail server, game server, or access your computer remotely, you need to open up a port or two so that outside traffic can get inside. This is called port forwarding, and it’s not nearly as complicated as it sounds.
Getting Started with Port Forwarding
Port forwarding is a technique used to allow external devices access to computers or other devices on a private network. This is done by mapping the internal IP address and port number of the device to an external IP address and port number. By doing this, any traffic sent to the external IP address and port number will be forwarded to the internal device.
Port forwarding can be used for many different applications such as web servers, email servers, file sharing, gaming and more. It is important to note that not all applications will work with port forwarding. In some cases, you may need to use a different technique such as VPN or SSH tunneling.
When configuring port forwarding, it is important to ensure that only trusted devices have access to the internal network. This can be done by setting up a firewall and only allowing connections from specific IP addresses.
General Port Forwarding Method
There are two ways to set up port forwarding: manual port forwarding and UPnP.
Manual port forwarding is when you manually enter the router settings to forward a specific port to a specific device on your network. UPnP is a more automated method where your wifi router detects when a device on your network is trying to access something on the internet and automatically opens the appropriate ports.
Manual Port Forwarding
To set up manual port forwarding, you’ll need to log into your router’s web interface and look for the port forwarding section. Each router is different, so consult your router’s documentation for specific instructions.
In the port forwarding section, you’ll need to create a new rule. Enter the port you want to forward, the IP address of the device you want to forward it to, and the protocol (TCP or UDP).
Save your changes and try accessing the service you’re trying to use. If it still doesn’t work, double check your router’s documentation or give their support line a call.
UPnP Port Forwarding
UPnP is a more automated method where your router detects when a device on your network is trying to access something on the internet and automatically opens the appropriate ports.
To set up UPnP, you’ll need to log into your router’s web interface and look for the UPnP section. Again, each router is different, so consult your router’s documentation for specific instructions.
Enable the UPnP feature and save your changes. Try accessing the service you’re trying to use. If it still doesn’t work, double check your router’s documentation or give their support line a call.
What is Port Forwarding Needed for?
Port forwarding is a technique that can be used to allow remote access to a computer or server on a private network. By using port forwarding, you can connect to a computer on the other side of the world as if it were on your local network.
There are many uses for port forwarding. Some common examples include:
– Remote desktop access: By forwarding port 3389 (the default port for Microsoft Remote Desktop), you can connect to a remote computer as if you were sitting in front of it.
– SSH access: By forwarding port 22 (the default port for SSH), you can connect to a remote server using a secure shell.
– Web servers: By forwarding port 80 (the default port for HTTP), you can host a website on your home computer.
Another important use of port forwarding is to accelerate the gaming experience and reduce lag. In order for your data to travel back and forth, both your computer and the game server need to have their ports open. Port forwarding for games makes it easier for you to open ports and enjoy limitless gaming with friends.
Port forwarding can be a complex topic, but it is important to understand the basics in order to properly configure it. With the proper understanding, port forwarding can be a useful tool for many different applications.
