Calls made to random port (1128, 1129)

[talibnawaz]

Our Open Edge Progress database is behind a firewall and is accessible on port 10100. But regardless of giving the port number in the connection string, we have noticed that additional calls are being made to random ports, e.g. 1128 and 1129 in the screenshot below that are blocked by the firewall.

Here's my code:

var builder = new JdbcConnectionStringBuilder
{
    FetchSize = -1,
    DriverPath = "mydriver.jar",
    DriverClass = "com.ddtek.jdbc.openedge.OpenEdgeDriver",
    JdbcUrl = "jdbc:datadirect:openedge://132.42.1.41:10100;databaseName=mydb;user=myuser;password=mypwd;"
};
Console.WriteLine(sql);
var connection = new JdbcConnection(builder);
connection.Open();

Since the subsequent calls to random port numbers are blocked, we never get a response back. Is there a way to control which port numbers will the library call?

@talibnawaz I'm sorry I'm not a primary developer, I just contributed once and answered a couple questions. I would recommend downloading the codebase, adding it to your solution, referencing it directly instead of the nuget package and stepthrough the code and see maybe where it could be coming from. otherwise if you do not find it, it could be the jar file. BUT I am not very familiar with this codebase. maybe @iodes or @evan-choi could shed some light if they have a moment
