To add a network port, you need to understand some basic concepts and steps. Network port is a mechanism to identify network services or applications, which is identified by the combination of IP address and port number. The following are the general steps to add a network port to a computer:

Understand the port

First, you need to know the different network ports and their uses. Common network ports are HTTP (port 80), HTTPS (port 443), FTP (port 2 1), SSH (port 22) and so on. Each port is usually associated with a specific network service or application.

Open the firewall port

If your computer has a firewall (antivirus software, the firewall that comes with the operating system, etc. ), you may need to configure a firewall to allow traffic from a specific port to pass through. This is usually done through firewall settings.

Configure a router/switch

If you want to use a specific port inside the LAN, you need to configure it on the router or switch. This usually involves port forwarding or virtual server setup to route external requests to the correct computer and port.

Check the application settings.

If you want to add a port to a specific application, you may need to check the settings or documentation of that application to learn how to configure it to use a specific port.

Start a service/application

Finally, make sure that the service or application that wants to use a specific port has been started on the computer. Different applications have different ways to specify the port they want to listen on.
