How to add Port 443 to the Windows Firewall in Windows 8,8

The port 80 and port 443 ports are listed with Firewalld as http and https services. To temporarily open both ports execute: # firewall-cmd --zone=public --add-service=http # firewall-cmd --zone=public --add-service=https Note, the above firewald commands will open HTTP and HTTPS port only temporarily. :80 and :443 refer only to the server port in use (i.e. it is "just a number") and carries no significance at all with regards to security. However, there is a strong convention to send http over port 80 and https over port 443, which makes the combinations in the question more than a little unorthodox. TCP port 443 is the default port used by HTTPS (Hypertext Transfer Protocol Secure), the protocol used to secure https:// websites, and used throughout the internet by banks, Gmail, Twitter, and many more essential web services. We can use any available port for HTTPS, however, for the sake of convention, 443 and 8443 are assigned for HTTPS (browsers automatically prefix with https when these port numbers are used), but we can even run HTTPS on port 80. In this case it is our responsibility to use https (if we don't indicate it, the browser will consider it a http link).

The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports. 15/11/2015 · It is not clear why port 443 was chosen. However, the previous RFC document had a gap from 374 through 512, but in RFC1700 the space from 375 to 451 was filled. It is most likely that the numbers were simply given in order of request. Have something to add to the explanation? 1/03/2018 · The Port 443, a web browsing port, is primarily used for HTTPS services. It is another type of HTTP that provides encryption and transport over secure ports.

If the HTTP port is 80, the HTTPS port must be 443. If the HTTP port is anything else, the HTTPS port must be 1 or higher, for example, 8530 and 8531. Note. When you configure the software update point to use HTTPS, the HTTP port must also be open. Unencrypted data, such as the EULA for specific updates, uses the HTTP port.
