How can I change addresses in WSDL published by SwitchYard?

Issue

• When I publish WSDL proxy to external parties, I can not give them (external parties) direct access to our integration server (FSW) as per our designed architecture. Hence, we are giving them address of our web server which is sitting on top of our integration server.
• While publishing proxy of web service, SwitchYard makes paths of schema file machine specific, which means SwitchYard adds FSW addresses to the published WSDL. I want to make these XSD addresses with the web server's IP and port rather than the FSW address.
