My understanding from reading the documentation is: Provider = Remote means the client is on the network, excluding 127.0.0.1 Provider = Loopback means the client is actually on the same OS instance as the FB3 engine, and it is using the 127.0.0.1 to access the database to avoid the "embedded server concept" from answering the request, as it would capture the DB file and will not allow any other clients from remote /network source. Engine12 = The local server takes control of the database as if it was an embedded server, killing all future chance of accessing the DB from the network, so Engine12 is if I understand correctly the way to talk to the DB engine in "exclusive" mode when you want to perform maintenance or work on the security database.
Is the above wrong?

So it is a required part of Firebird 3.

DatabaseAccess = None AuthServer = Srp AuthClient = Srp UserManager = Srp Providers = Remote WireCrypt = Enabled WireCompression = false ServerMode = Super I've noticed the network applications that access the FB3 db failed to connect unless I add the Engine12 to the providers list, would that be because FB3 engine needs Engine12 to access the security DB at the handshake? The way the network apps try to talk to the FB3 server is via ODBC and the database field is defined as 192.168.xxx.xxx:MyDbName , I also tried with 192.168.xxx.xxx/3050:MyDbName and made no difference, any ide why Engine12 is required? Cheers, Fabian
