C＃-WCF可在本地计算机上运行，​​但不能通过网络运行

Question

我在C＃应用程序中使用WCF遇到问题。 当服务器和客户端在同一台PC上时，我可以调用服务，但是如果服务器和客户端在不同的PC上，则请求超时。 我已经打开了防火墙中的端口（我使用端口9998），甚至尝试关闭防火墙。 服务器的app.config如下所示：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/></startup>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="SMS_ServiceBehavior">
          <serviceMetadata />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="SMS_ServiceBehavior" name="SMSapplication.SMS_Service">
        <endpoint address="http://10.20.5.100:9998/SMS_Service" binding="basicHttpBinding"
          bindingConfiguration="" name="SMS_ServiceEndpoint" contract="SMSapplication.ISMS_Service" />
        <endpoint address="http://10.20.5.100:9998/mex" binding="mexHttpBinding"
          bindingConfiguration="" name="mex" contract="IMetadataExchange" />
      </service>
    </services>
  </system.serviceModel>
</configuration>

是否有人知道我还能尝试什么或错误可能出在哪里？

客户端的配置文件如下所示：

    <?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="SMS_ServiceEndpoint" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:9998/SMS_Service" binding="basicHttpBinding"
                bindingConfiguration="SMS_ServiceEndpoint" contract="SMS_Service.ISMS_Service"
                name="SMS_ServiceEndpoint" />
        </client>
    </system.serviceModel>
</configuration>

我注意以下代码：

SMS_Service.SMS_ServiceClient client = new SMS_Service.SMS_ServiceClient();
client.Endpoint.Address = new EndpointAddress(new Uri("http://10.20.5.100:9998/SMS_Service"), client.Endpoint.Address.Identity, client.Endpoint.Address.Headers);
client.Open();
client.DoWork("test");
client.Close();
