How to host wcf in application server and how to access this application server in web server?

Hi All,

I working with mobile application development. here i wants solution for Web server and Application server WCF Service hosting in IIS Server.

The Web server in public network (which is contains static ip address, i can access from internet) and application server in local network (WCF Service is hosted in application server). The ultimate plan is access the wcf service via web server.

Note : My wcf service contains both get and post method and it return output format as JSON.

Thanks in advance.
