Proper way to allow Power BI Gateway access to Database?

Hi Anonymous ,

For communication to the SQL Server database engine and for intersite replication, you can use the default SQL Server port or specify custom ports:

1.Intersite communications use:

(1).SQL Server Service Broker, which defaults to port TCP 4022.

(2).SQL Server service, which defaults to port TCP 1433.

2.Intrasite communication between the SQL Server database engine and various Configuration Manager site system roles defaults to port TCP 1433.

3.Configuration Manager uses the same ports and protocols to communicate with each SQL Server Always On availability group replica that hosts the site database as if the replica was a standalone SQL Server instance.

When you use Azure and the site database is behind an internal or external load balancer, configure the following components:

1.Firewall exceptions on each replica

2.Load-balancing rules

Configure the following ports:

1.SQL over TCP: TCP 1433

2.SQL Server Service Broker: TCP 4022

3.Server Message Block (SMB): TCP 445

4.RPC Endpoint Mapper: TCP 135

For more information of ports of gateway and firewall, you can refer this documentation below:

Hope this helps you.
