Access the WCF service from another computer

I spend hours and hours on it and just can't make it work. Perhaps my understanding of hosting the WCF service and creating a client for it is wrong.

A WCF service has been added to my website with the following configuration ...

<system.serviceModel>

<bindings>
  <wsHttpBinding>
    <binding name="Binding1">
      <security mode="None">
        <transport clientCredentialType="None" />
        <message establishSecurityContext="false" />
      </security>
    </binding>
  </wsHttpBinding>
</bindings>

    <behaviors>
        <serviceBehaviors>
            <behavior name="MyWCFWebApp.Service1Behavior">
                <serviceMetadata httpGetEnabled="true"/>
                <serviceDebug includeExceptionDetailInFaults="false"/>
            </behavior>
        </serviceBehaviors>
    </behaviors>

    <services>
        <service behaviorConfiguration="MyWCFWebApp.Service1Behavior" name="MyWCFWebApp.Service1">
            <endpoint address="" binding="wsHttpBinding" contract="MyWCFWebApp.IService1" bindingConfiguration="Binding1">
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        </service>
    </services>

</system.serviceModel>

When I launch the website through Visual Studio using the build on the web server, I can access the web service through http: // localhost: 9988 / Service1.svc

but...

When placing a website through the cassiniDev server, binding to ip and host name, I can access the wcf service through http: // localhost: 9988 / Service1.svc , but as soon as I try to access the wcf service using ip or hostname http://10.111.202.73:9988/Service1.svc , it returns the following error:

" " http://10.111.202.73:9988/Service1.svc ". IIS WAS.
