Subject Occasionally need to specify port number in connectiong string to connect over network
Author Rodney Tapit
We are using Firebird 2.5 in our Windows (7, 8,10) based application in a network situation.
We use a different port from the default 3050 for the application. We have edited the RemoteServicePort in the firebird.conf to reflect the port number we are using.
The client connection strings we normally use is:

But occasionally, on some network installations in order to establish connection we have to specify the port number:

We would rather not specify the port number on the connection string for security reasons.

Can you please advise what factors govern whether the port number needs to be included given that the RemoteServicePort  is defined in the firebird.conf?
