CWP panel + Nginx

i have CWP7 panel with public and private ip address. i have many web sites in my private network and all of them in different servers. i want to write CWP7 public ip to my websites domain name and redirect from CWP7 to my private network webservers to nginx. Can somebody explain how to do this? I want to redirect any http to https where i should create SSL certs in CWP7 or in my webservers? CWP7 select webservers is apache only mode

you need configure proxy for your domains (but i recomend for that nginx its much faster in that role).

SSL you need to create/add in cwp -its enought, webservers dont't need have SSL (can have but it doesn't matter).

You alright about (  webservers dont't need have SSL ) I just like to add a little more info about that please . 
Google chrome ( and I guess other browsers since I didnt test them )  will not allow you to use auto fill username and password or even save them if you dont have a valid ssl for the webserver login page URL
