Teach me how to use proxy in genymotion.

Genymotion is an android virtual machine on your PC. I am currently having troubles how to use a proxy in it that routes all traffic (including apps) trough the proxy. I know that I can go to wifi settings and set proxy there but that only sends browser traffic trough the proxy. I am looking for someone to show me how to use a proxy in genymotion as I have described above, so that the proxy affects all apps. I am currently looking at 2 apps that could be able to do it. One is ProxyDroid and the second one is Postern (you can find these in the Google Playstore). Proxydroid requires to root the phone, which I don't know how to do. That is why I am writing here. Postern whenever I setup a proxy on this app the genymotion virtual machine always freezes and restarts. Maybe there is another better app that I should use, I don't know. I will pay anyone who can solve this problem for me.
