Side note: UDP port 1443 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 1443 makes possible the transmission of a datagram message from one computer to an application running in another computer.
How do I check if port 1443 is open?
Simplest way to do that is probably (on the server, in a cmd window) netstat -an | find “1443” and see what you get back. Second, if it’s a TCP connection you’re looking for, you may be able to telnet
How do I find my TCP and UDP port number?
All you have to do is type “netstat -a” on Command Prompt and hit the Enter button. This will populate a list of your active TCP connections. The port numbers will be shown after the IP address and the two are separated by a colon. For instance, if your IP address is something like 192.168.
