Replace the Localhost with IP address

Question

Hello,
Please help me on this issue,

I have created a WCF server and trying to use this in C# asp .net website available on same machine.

However in SCF service we.config It has default endpoint address with 'localhost'. I just want to replace this with IP address of machine so that client app from diff machine can also call this service.

Here is my Webservice config file..

------------------------------------------------------

    <system.serviceModel>
   
   
   
        <services>
   <service behaviorConfiguration="PriceServer.Service1Behavior"
    name="PriceServer.PriceService">
    <endpoint address="http://localhost:50161/PriceService.svc" behaviorConfiguration=""
     binding="mexHttpBinding" bindingConfiguration="" contract="PriceServer.IPriceService">
     <identity>
      <dns value="localhost" />
     </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" bindingConfiguration=""
     contract="IMetadataExchange" />
   </service>
  </services>
        <behaviors>
     
            <serviceBehaviors>
     
                <behavior name="PriceServer.Service1Behavior">
                    <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
                    <serviceMetadata httpGetEnabled="true"/>
                    <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
                    <serviceDebug includeExceptionDetailInFaults="false"/>
         
        
                </behavior>
            </serviceBehaviors>
     
     
      <!-- Adding to enable the calling from client side-->

      <endpointBehaviors>
        <behavior name="ServiceAspNetAjaxBehavior">
          <enableWebScript/>
        </behavior>
      </endpointBehaviors>
    </behaviors>

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
    <!-- Adding to enable the calling from client side-->

  <!--  </behaviors>-->
   
    </system.serviceModel>

thanks

This seems like a question not related to Config Services itself; but rather a generic WCF question. 

Using localhost should typically allow remote clients to connect up over a specific IP address or DNS name; as this really is telling the services to listen on all IP's on the machine; I do believe.  However, this can become an issue if endpoint identities are used, such as with message level encryption; where certs expect incoming requests to match a specific DNS name, etc.  But assumig this is not the issue, yet you want to restrict the service to listen on a specific IP address:

1) Assuming you know the IP (it is static vs. DHCP defined); you can simply put this IP address in your endpoint definition instead of localhost.

2)  You must also create a binding configuration, and in this binding configuration set the property for HostNameComparison to Exact vs. StrongWildCard.


Finally, Config Services takes care of much of this for you; typically creating endpoints on the DNS host name, meaning listening on every IP address on that host.  It provides a mechanism in config, to override on a per-endpoint basis, with the use of a specific IP address (or alternate hostheader name in IIS, if desired); but you still have to use binding configs with HostNameComparison set to Exact for those endpoints you want to constrict to a single IP address; see page 32 of the Config Service Technical Guide.
