WCF Custom binding - send timeout always reached

Question

I have a wcf service that needs to implement callbacks and be hosted on IIS 6.0. Since IIS 6.0 doesn't support the net.tcp binding, I decided to use a custom binding because the service is accessed by different clients in different timezones and, using custom binding, I can set the allowed clock skew time to values other than the default one.

Here is my server config file:

<bindings>
  <customBinding>        
    <binding name="pscNetBinding" openTimeout="00:10:00">          
      <reliableSession acknowledgementInterval="00:00:00.2000000"
  flowControlEnabled="true" inactivityTimeout="23:59:59"
  maxPendingChannels="128" maxRetryCount="8" maxTransferWindowSize="128"
  ordered="true" />
      <compositeDuplex />
      <oneWay maxAcceptedChannels="128" packetRoutable="false">
        <channelPoolSettings idleTimeout="00:10:00"
  leaseTimeout="00:10:00" maxOutboundChannelsPerEndpoint="10" />
      </oneWay>
      <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
  messageVersion="Default" writeEncoding="utf-8">
        <readerQuotas maxDepth="2147483647"
  maxStringContentLength="2147483647" maxArrayLength="2147483647"
  maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      </textMessageEncoding>
      <httpTransport manualAddressing="false"
  maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
  allowCookies="false" authenticationScheme="Anonymous"
  bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
  keepAliveEnabled="true" maxBufferSize="2147483647"
  proxyAuthenticationScheme="Anonymous" realm="" transferMode="Buffered"
  unsafeConnectionNtlmAuthentication="false" useDefaultWebProxy="true"/>
    </binding>
  </customBinding>
</bindings>

<services>
  <service name="SchneiderElectric.PSCNet.Server.Services.PSCNetWCFService" behaviorConfiguration="Behaviors1">
    <host>
      <baseAddresses>
        <add baseAddress ="http://10.155.18.18:2000/PSCNet"/>
      </baseAddresses>
    </host>
    <endpoint address="" binding="customBinding"    bindingConfiguration="pscNetBinding"
                                contract="SchneiderElectric.PSCNet.Server.Contracts.IPSCNetWCFService"/>
  </service>
</services>    
<behaviors>
  <serviceBehaviors>
    <behavior name="Behaviors1">
      <serviceMetadata httpGetEnabled = "true"/>
      <!--<serviceThrottling maxConcurrentCalls="2048" maxConcurrentSessions="2048" maxConcurrentInstances="2048" />
      <dataContractSerializer maxItemsInObjectGraph="2147483647" />-->
    </behavior>
  </serviceBehaviors>
</behaviors>

Client config file:

  <bindings>
    <customBinding>
      <binding name="pscNetBinding" openTimeout="00:10:00">            
        <reliableSession acknowledgementInterval="00:00:00.2000000"
    flowControlEnabled="true" inactivityTimeout="23:59:59"
    maxPendingChannels="128" maxRetryCount="8" maxTransferWindowSize="128"
    ordered="true" />
        <compositeDuplex />
        <oneWay maxAcceptedChannels="128" packetRoutable="false">
          <channelPoolSettings idleTimeout="00:10:00"
    leaseTimeout="00:10:00" maxOutboundChannelsPerEndpoint="10" />
        </oneWay>
        <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
    messageVersion="Default" writeEncoding="utf-8" >
          <readerQuotas maxDepth="2147483647"
    maxStringContentLength="2147483647" maxArrayLength="2147483647"
    maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
        </textMessageEncoding >
        <httpTransport manualAddressing="false"
    maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
    allowCookies="false" authenticationScheme="Anonymous"
    bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
    keepAliveEnabled="true" maxBufferSize="2147483647"
    proxyAuthenticationScheme="Anonymous" realm="" transferMode="Buffered"
    unsafeConnectionNtlmAuthentication="false" useDefaultWebProxy="true" />                    
      </binding>
    </customBinding>
  </bindings>
  <client>
    <endpoint address="http://10.155.18.18:2000/PSCNet" binding="customBinding"
        bindingConfiguration="pscNetBinding" contract="PSCNetWCFService.IPSCNetWCFService"
        name="pscNetBinding" />
  </client>

If I use the server and client on the same machine, everything works fine. If I run them on different machines, I get the following error:

Could not connect to http://10.155.18.198:9000/e60ba5b3-f979-4922-b9f8-c820caaa04c2. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.155.18.198:9000.

Can anyone in the community help me in this regard?

Can you show the part of the config where you're defining the customBinding? Maybe you just didn't paste that part in, but when you define a custom binding, you have to specify an encoding and a transport at minimum - something like this:

<bindings>
    <customBinding>
        <binding name="MyCustomTextTcpBinding">
            <textMessageEncoding />
            <tcpTransport />
        </binding>
    </customBinding>
</bindings>

Can you also paste in the part where you're defining your "pscNetBinding" bindingConfiguration?
