Port 1433 for TCP is needed to connect to the SQL database instance. By default, SQL will attempt to use 1433. If that port is unavailable, it will automatically choose another port.TCP Introduction

SQL Server Browser service uses UDP static port 1434. It reads the registry for the assigned TCP port. SQL Server client library connects and sends a UDP message using port 1434. SQL Server Browser service gives back the port number of a specific instance.

What is MS SQL port
The SQL Server Database Engine listens on port 1433 for TCP/IP connections and port 1434 is used for UDP connections by default. Three different ways to identify the port used by an instance of SQL Server: Reading SQL Server Error Logs. Using SQL Server Configuration Manager. Using Windows Application Event Viewer.
Is MySQL port 1433 or 3306 : Port 3306 is the default port for the classic MySQL protocol (port), which is used by the mysql client, MySQL Connectors, and utilities such as mysqldump and mysqlpump.
Unfortunately, SQL Server is not secured by default. Other machines communicating with it over TCP Port 1433 are doing so in clear-text, and a sniffer like WireShark could intercept those communications. For a long time, clear-text inside of a network's perimeter was commonplace. This bot identifies when a Resource Access List is created whether it allows unrestricted access (0.0. 0.0/0) to TCP port 1433 (Microsoft SQL Server).
What is 1433 vs 1434 port
Select the Port type of the rule. Specify the ports 1433 and 1434 to which this rule applies inside the Specific local ports area. In this case, 1433 stands for the SQL server, and 1434 for the SQL server browser.Port 1433 provides data integrity because TCP creates a secure, authenticated connection before exchanging data streams. Unlike UDP, the TCP protocol guarantees the proper delivery of data.TCP port 1433 is the default port for communication between Microsoft SQL Server and its applications. SQL Server powers many of the world's top data-driven solutions, and port 1433 is widely used to connect to the database. Port 3306
Port 3306 is the default port for the classic MySQL protocol (port), which is used by the mysql client, MySQL Connectors, and utilities such as mysqldump and mysqlpump.

Can MySQL use port 1433
Port number 1433 is commonly used for MySQL server. Username: the user name on the SQL server, with "sa" being a commonly used name. The MySQL client, utilities like mysqldump, and MySQL connectors all utilize port 3306 as the default one.It is used for both standard SQL Server connections as well as connections using the SQL Server Browser Service. If unrestricted inbound access to TCP port 1433 is allowed, it can expose the SQL Server to unauthorized access, data theft, and other security risks.
Does SQL Server use 1433 or 1434 : Select the Port type of the rule. Specify the ports 1433 and 1434 to which this rule applies inside the Specific local ports area. In this case, 1433 stands for the SQL server, and 1434 for the SQL server browser. In this step, leave the default selection: Allow the connection.
