当我尝试使用WCF客户端和服务器登录到另一台PC上的服务器时，我在客户端部分遇到安全协商异常。它在局域网中工作，但是当我使用端口转发和静态IP地址在Internet上使服务器联机时，我在客户端中遇到了这个例外。
客户端配置：

这是一个例外：

was unhandled by user code Message=A
remote side security requirement was
not fulfilled during authentication.
Try increasing the ProtectionLevel
and/or ImpersonationLevel.

InnerException:
服务器或客户端部分的问题是否存在此异常？
答案 0 :(得分：1)
那么您的客户通过互联网访问该服务？在这种情况下，您无法使用Windows安全性。它仅适用于本地网络/同一Windows domain。
答案 1 :(得分：0)
对于此异常，您应在服务器和客户端None上建立安全模式：
<security mode="None">
<transport clientCredentialType="None">
</transport>
<message clientCredentialType="None" />
</security>
它对我有用，但我有另一个例外：
套接字连接已中止。这可能是由于处理消息时出错或远程主机超出接收超时或基础网络资源问题而引起的
