How to connect an MSSQL database engine to a local network I need to let my public IP connect to a database that is located within the same local network.

Ex: MY public IP is: 190.222.222.222 The local IP of that PC is: 1.1.1.4 And this server already has an MSSQL (Localhost) engine. This means that if I connect to the Public IP it automatically calls me the LOCALHOST database engine.

I need that at the time of connecting to the public IP this call / connect to the local server database engine 1.1.1.7

The connection between server 1.1.1.4 and 1.1.1.7 is working. The firewall ports are open
the proper way - you need run Configuration Manager and check if tcp/ip support enabled for all necessary interfaces.
