Java Socket技术绑定本地接口（ppp0的）(Java Socket Bind Local

我已经使用ppp0的端点通过这种方式tryied释放一个java socket连接：

Socket socket = new Socket(InetAddress.getByName("200.147.67.142"), 80, InetAddress.getByName("189.116.7.204"), 4447);

其中189.116.7.204是ppp0的界面和200.147.67.142目标IP地址。

问题是：TimeoutException异常

我的网络配置：

ifconfig -a
