What is port forwarding?
What will be an ideal response?
Routers can be configured to support port forwarding. On a computer, software ports (not to be confused with physical interfaces on the rear of the computer that are also called "ports" such as USB or serial ports) are numbered software connections that a computer uses to identify different types of network traffic. For example, port 20 is commonly used for FTP transfers. For security reasons, software ports on a router are closed so that traffic cannot flow through them. In some instances, it may be necessary to assign an unused software port number to a service that is associated with a software application that runs on the computer. This is known as port forwarding.
