Host HTTP WCF Service in a Windows Service

I'm hosting a HTTP WCFService in a Windows Service, in local network it works perfectly, but if the client is in another network and try to connect with de public IP doesn't work.

Config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" />
  </system.web>
  <!-- When deploying the service library project, the content of the config              
  file must be added to the host's 
  app.config file. System.Configuration does not support config files for         
  libraries. -->
  <system.serviceModel>
    <services>
      <service name="WCFService.ServiceBehavior">
        <endpoint address="" binding="wsHttpBinding"     
          contract="WCFService.ServiceContract">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" 
        contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:80/WCFService/service/" />
      </baseAddresses>
    </host>
  </service>
</services>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, 
          set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="False" />
    </behavior>
  </serviceBehaviors>
</behaviors>
  </system.serviceModel>

</configuration>

The service metadata publishes http://localhost:80/WCFService/service/ to the client. This URL is not accessible from outside the local host.

In order to access the service from another network using a public IP the service metadata should publish http://PUBLIC_IP_ADDRESS/WCFService/service/ to the client. This can be done dynamically depending on the URL used by the client. Just add useRequestHeadersForMetadataAddress to service behaviors.

<behaviors>
    <serviceBehaviors>
       <behavior name="...">
         ...
         <useRequestHeadersForMetadataAddress />
       </behavior>
    </serviceBehaviors>
</behaviors>

I suspect that when you give a config like this:

<add baseAddress="http://localhost:80/WCFService/service/" />

It would be listening in the loopback address due to the usage of locahost. Change this to the actual public IP address (i.e., not 127.0.0.1) or Server name and check again.
