Custom WCF app hosted in SharePoint _Layouts errors when access form client machine.

Question

Hello,  I have a very strange behavior of the WCF dotnet application hosted in SharePoint server. When I run the application on SharePoint server by accessing
http://SPSServer/_layouts/WCFCustApp loads correctly and executs all functionalities. However from the client machine when I access the same application, it throws below error:
[12/13/2013 8:31:02 PM] System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue.

Both I verified and none of those helped to resolve the issue. Will you please let me know if anyone else has encountered this problem?
I have noticed the WCF project has one web.config and it does not take from it when the application is deployed to SharePoint site collection. I made sure the sharepoint web.config file has all tcpip and other web service configurations. It works great on the
server and just failed to run from client machine :(
Experts any other solutions that you might have experienced?
Thanks
