OpenVPN Configuration CentOS - XP ( Server - Client )

    This is an open source application. It provides ‘VIRTUAL PRIVATE NETWORK’. It provides tunneling in which we can transmit packets securely. The main aim of using any VPN is to secure the network.

And as a proof we will also analyze the packet through tcpdump.
