我试图连接到我的程序，该程序在NAT后面使用FreePastry但没有在哪里。 mIP是我的公共IP，mBootport和mBindport是50001.我已经将我的路由器中的这些端口转发到我的计算机上，但它不起作用。我没有禁用防火墙。我断开了路由器并直接连接到互联网，stil它不起作用。它唯一一次在我的本地网络上工作。所以在配置文件的代码中出现了大多数错误，但我看不出有什么问题。

答案 0 :(得分：2)
不确定你的意思是“不工作”。要测试客户端和服务器之间的连接（坐在NAT后面），只需在客户端执行类似“telnet mIP mBindport”的操作，假设您有一个telnet实用程序（默认情况下在Linux和Mac上，您可以安装一个，比如Windows上的nc（“netcat”）。
如果端口转发设置正确，则在与服务器建立TCP连接时，应看到如下内容。
Connected to localhost.
Escape character is '^]'.
TCP会话设置正确后，您可以停止“telnet”程序并使用真实客户端（在java中）与服务器通信，它应该可以正常工作。
如果未设置TCP会话，您可能需要检查服务器端。使用wireshark或tcpdump来捕获具有过滤器“tcp port 50001”的数据包，并运行上面的telnet命令以检查是否有TCP数据包进入。
如果wireshark或tcpdump中没有显示任何内容，那么您的防火墙（如端到端转发）设置不正确。
如果TCP数据包确实显示在wireshark或tcpdump中，那么您的服务器程序可能出错。使用命令（linux）检查它绑定的IP地址：
netstat -antp | grep 50001
（在Windows上，命令略有不同）。
通常它应该绑定到IP地址0.0.0.0（所有ip），如果没有，你应该检查它绑定的IP是否具有到外部世界（在NAT之外）的连接/路由。
祝你好运。答案 1 :(得分：1)
我会尝试将您的IP设置为Free Pastry正在运行的计算机的本地IP。听起来好像计算机正在获取信息，但Free Pastry正在寻找不同的地址。如果你将你的mIP设置为本地，我认为它会起作用。如果它在路由器/ NAT后面，那就是这样。
端口转发将端口50001上的公共IP数据包转发到您设置的任何端口上的内部计算机IP，通常是相同的50001.如果您将程序设置为侦听公共IP，则无法访问它不会接受任何数据包/消息。设置为侦听计算机IP或0.0.0.0/localhost，它应该接受该端口上的任何数据包/消息。
