Android：代理（中继）服务器请求

Question

I have a server and an android app. My server want to request a destination but with the IP of the android device that my app is running on. So I need to proxy the requests (relay them) in my app so the destination could see the client's IP but the server. You can see my explanation in the picture:

How can I do this in my app?

Answer 1

Yes this could be done but not just with relays; you also need to port forwarding mechanism in between. Here is how I would try to do this:

Local portforward the requests of the server onto a dedicated port on your android device and then from their call the Destination server via your relay mechanism which could be fulfilled very succicntly by LittleProxy like solution.
