Its not a DNS issue because clients are not even able to ping Google public DNS IP address 8.8.8.8. Client is able to connect and ping to server, but the problem is that client is not able to access to internet. I have successfully been able to run server and client. I am trying to setup OpenVPN server on my Mac Mini along with TunnelBlick.
