In this lesson, we explore the concept of well-known ports, the standardized communication endpoints used by common services and protocols. Learn about port numbers such as 80 (HTTP), 443 (HTTPS), 22 (SSH), 53 (DNS), and others. Understand how these ports facilitate network communication and their importance in VPN configuration and security. By the end of this video, you’ll be familiar with well-known ports and how to manage them effectively in your network setup.
