I want to setup an OpenVPN Server and after a week of trying day and night (no Linux Knowledge) I was able to successfully connect to the Server using OpenVPN GUI but now that I can Connect there is no ping 8.8.8.8 and the webpages won't open.
Server is Running: CentOS 7 X64
Client is Running: Windows 10 Pro Build 10586.17 X64 w/ Kaspersky Internet Security
This is my server Config

Below is my route print after establishing the connection to my Server.
