无法在Mac中打开Azure SQL数据库的端口1433

我正在尝试在Java应用程序上访问Azure托管的SQL数据库。我使用nmap检查了端口1433，它显示它已关闭：

Starting Nmap 7.12 ( https://nmap.org ) at 2016-09-02 09:44 PHT
Nmap scan report for localhost (127.0.0.1)
Host is up (0.00014s latency).
Other addresses for localhost (not scanned): ::1
PORT     STATE  SERVICE
1433/tcp closed ms-sql-s

我已经编辑了/etc/pf.conf并重新启动了Mac，但是该端口仍然关闭。这是我的pf.conf：

scrub-anchor "com.apple/*"
nat-anchor "com.apple/*"
rdr-anchor "com.apple/*"
dummynet-anchor "com.apple/*"
anchor "com.apple/*"
load anchor "com.apple" from "/etc/pf.anchors/com.apple"
pass in proto tcp from any to any port 1433

另外，我的防火墙设置为关闭。

我的Java应用抛出此错误：

Error starting database: The TCP/IP connection to the host flowengine7.database.windows.net, port 1433 has failed. Error: "Connection timed out: no further information. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".

Java代码：

 String connectionString =
                "jdbc:sqlserver://dbName.database.windows.net:1433;database=dbName;user=user@@user;password=passwordhere;encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30;";

        Connection connection = null;

        try {
            connection = DriverManager.getConnection(connectionString);
            println 'connected';
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        finally {
            if (connection != null) try {
                connection.close();
            } catch (Exception e) {
            }
        }
