Port numbers are like extensions to your IP address. For example, your computer's IP address is 53.125.105.18, while the file transfer protocol (FTP) port number is 20. Thus, the IP for an open FTP port would be 12.345.678.90:20. By seeing this address, the server will "understand" your request.
A process called network port scanning detects test messages at each port number to identify which ports are open. Network professionals use port scanning as a tool to measure exposure to attackers and often lock down networks by closing non-essential ports. Hackers, in turn, use port scanners to probe networks for open ports that may be The local port number in the firewall rule needs to be whatever port number your SQL Server is listening on, in this case port 1433. (Typically, you would only specify a particular remote port when creating an outbound rule; for example, you would specify remote port 80 if you wanted to create a rule blocking outbound HTTP traffic.) Local forwarding is used to forward a port from the client machine to the server machine. Basically, the SSH client listens for connections on a configured port, and when it receives a connection, it tunnels the connection to an SSH server. The server connects to a configurated destination port, possibly on a different machine than the SSH server. Port St Lucie.

Port numbers are assigned to applications and their communications on a local area network (LAN). They help to keep one particular "conversation" distinguishable from another. Default port numbers have been assigned to most applications or services. Local port forwarding is the most common type of port forwarding. It is used to let a user connect from the local computer to another server, i.e. forward data securely from another client application running on the same computer as a Secure Shell (SSH) client.
