Connect to SQL Server Through a Proxy Server (SQL Server Configuration Manager)
Updated: December 15, 2016
This topic describes how to connect to SQL Server through a proxy server in SQL Server 2016 by using SQL Server Configuration Manager. To listen remotely by way of Remote WinSock (RWS), define the local address table (LAT) for the proxy server so that the listening node address is outside the range of LAT entries.
Follow the steps in Configure a Server to Listen on a Specific TCP Port (SQL Server Configuration Manager) to determine which TCP/IP ports are used by the Database Engine, or to configure the Database Engine to use a desired port.
In your proxy server define the local address table (LAT) for the proxy server so that the listening node address is outside the range of LAT entries. For more information, see your proxy server documentation.
