WCF wsDualHttpBinding 双工通信 寄宿服务器的IIS , 客户端使用的时候总是超时。

服务器端：

[ServiceContract(SessionMode=SessionMode.Required ,CallbackContract=typeof(IEHAOYAOCallback))]
    public interface IEHAOYAOMessageService
    {
        [OperationContract(IsOneWay = false, IsInitiating = true, IsTerminating = false)]
        string Join(string agentId);
        [OperationContract(IsOneWay = true, IsInitiating = false, IsTerminating = false)]
        void Leave();
        [OperationContract(IsOneWay = false,IsInitiating = false, IsTerminating = false)]
        string ClearWait();
        [OperationContract(IsOneWay = false, IsInitiating = false, IsTerminating = false)]
        string CloseSeesion(string customerOpenID);
        [OperationContract(IsOneWay = true, IsInitiating = false, IsTerminating = false)]
        void GetWaitCustomer();
        [OperationContract(IsOneWay = false, IsInitiating = false, IsTerminating = false)]
        string UpdateStatus(int status);


    }

    public interface IEHAOYAOCallback
    {
        [OperationContract(IsOneWay = true)]
        void ReceiveTextMessage(TextEntity messageEntity);
        [OperationContract(IsOneWay=true)]
        void ReceiveImageMessage(ImageEntity messageEntity);
        [OperationContract(IsOneWay = true)]
        void ReceiveVoiceMessage(VoiceEntity messageEntity);
    }

服务器端配置文件：

<configuration>
	<system.web>

	</system.serviceModel>
	<system.webServer>
		<modules runAllManagedModulesForAllRequests="true"/>
	</system.webServer>
</configuration>

客户端：

 private void Form1_Load(object sender, EventArgs e)
        {
            client = new EHAOYAOMessageServiceClient(new System.ServiceModel.InstanceContext(this));
        }

        private void button2_Click(object sender, EventArgs e)
        {
           MessageBox.Show(client.Join(txtAgent.Text));
        }

但是我关闭了客户端机子的防火墙就能正常访问了
