服务上的跟踪显示了来自客户机的连接详细信息，因此它必须在某种程度上通过。此外，当我在与服务相同的机器上运行客户机时，一切工作都很完美。要使远程连接正常工作，我可能需要做什么？

这很可能是防火墙问题-wsDualHttpBinding尝试打开从服务器到客户端的第二个连接，该连接可能会被任何防火墙阻止

NetTcpBinding对于双工通信来说更加健壮，正如我在博客中所写的

如果问题确实出在客户端上，请查看您的客户端配置-您已将发送超时值设置为10秒。您是否尝试增加超时值以查看这是否解决了问题？是的，我已将其设置为1分钟，但仍然会出现相同的错误。您认为问题出现在客户端而不是服务上的积极程度如何？我这样做是因为服务可能遇到异常或其他问题，并且超过了超时时间。如果你还没有考虑的话，还有另一种可能性。你尝试过将超时值更改为更大的值，包括RealEvTeMeUT和StimeTimeOUT吗？
