You should explicitly allow traffic for ports 80 and 443 to keep your site publicly accessible while restricting access to management ports like SSH (22) to specific IP addresses. A port acts as a communication endpoint on a server, allowing different services to operate simultaneously on a single IP address.
Understanding Network Ports Function and Their Role in Communication
While the IP address directs data to the correct server, the port number directs that data to the correct application or service running on that server. To make this local site accessible to testers or partners over the internet, you use port forwarding services like ngrok.
These well-known ports are reserved for specific protocols to avoid conflict and confusion. It works in conjunction with an IP address to form a socket, which is the foundation of network communication.
Understanding Network Ports Function and Their Role in Communication
When you type a URL into your browser, the standard web traffic uses port 80 for HTTP or port 443 for HTTPS, but the digital infrastructure behind this simple action is much more complex. During development, you often run a local server on your machine, typically accessible at localhost:8000 or a similar address.
