How to Open Port in Windows Virtual Server

What is Port?

Port numbers are associated with TCP/IP network connections. A port number is a way to identify a specific process to which an Internet or other network message is to be forwarded when it arrives at a server. They allow different applications on the same computer to share network resources simultaneously. Home network routers and computer software work with these ports and sometimes support configuring port number settings.

How Does Port Numbers Work?

Port numbers relate to network addressing. In TCP/IP networking, both TCP and UDP utilize their own set of ports that work together with IP addresses.

In both TCP and UDP, port numbers start at 0 and go up to 65535. Numbers in the lower ranges are dedicated to common Internet protocols (like port 80 for HTTP and port 443 for HTTPS).
