在ubuntu上通过公共IP设置RMI引发NotBoundException

试图在ubuntu上通过公共IP设置RMI，但徒劳无功。我已经设置了http隧道。RMI服务器/小程序客户端在局域网上成功运行，ubuntu作为RMI服务器。通过internet，我能够在1099上将对象导出到固定端口1100上成功地运行服务器。我已经将1099和1100端口转发到ubuntu 192.168.1.XXX的本地IP。我还在rmi服务器和客户端上设置了以下内容

[rmiHostName = public ip]

//configuration
System.setProperty("java.security.policy","http://"+rmiHostName+"/basedir/rmi/java.policy");
System.setProperty("java.rmi.server.hostname",  rmiHostName);//external ip address
System.setProperty("java.rmi.server.codebase",http://"+rmiHostName+"/basedir/rmi/xxx-xxx-1.0.jar"); 

然而，我得到了以下例外：

你们能帮我解决这个问题吗

java.rmi.NotBoundException: //public-ip:1099/MyServer

您没有以MyRegistry的名义将远程对象绑定到位于//public ip:1099的注册表中。

谢谢您的快速响应。实际上，我已按如下方式绑定：rmiReg.rebind（“/”+rmiHost+”：“+rmiPort+”/“+”MyServer“，remoteObj）；其中rmiHost是ubuntu服务器192.168.1.XX的本地静态ip客户端通过公共静态ip 59.192.XX.zz访问非常感谢。我现在可以将其与公共ip正确绑定。现在客户端小程序正在尝试连接到我的ubuntu服务器上的随机端口。我将客户端小程序引发的错误粘贴到下面：网络：连接到代理=直接网络：连接代理=直接网络：连接代理=直接网络：连接代理=直接java.rmi.ConnectException:连接拒绝主机：公共ip；嵌套的异常是：java.net.ConnectException:Connection拒绝：connect at sun.rmi.transport.tcp.TCPEndpoint.newSocket（未知源代码）at java.net.AbstractPlainSocketImpl.connectToAddress（未知源代码）I服务器上只有两个端口打开，即1099和1100。如何修复aplet请求中的端口，使其始终像公共ip:1099一样连接服务器？请帮助。谢谢。我将远程对象绑定到公共ip上，可以从客户端连接注册表。但是，客户端正在尝试通过服务器上的随机端口进行连接，因此无法与服务器通信，因为这些端口未打开。您能帮我吗？
