How to Install OpenVPN Access Server on Ubuntu 12.04.2 LTS Server

Introduction
OpenVPN Access Server, from the official website is "a full featured SSL VPN software solution that integrates OpenVPN server capabilities, enterprise management capabilities, simplified OpenVPN Connect UI, and OpenVPN Client software packages that accommodate Windows, MAC, and Linux OS environments and mobile application for both Android and iOS platforms"

OpenVPN's website already blocked in Egypt by ISPs "TE-Data and LINKdotNET"

Installing
Let's begin by logging in as the root user. From here, download the OpenVPN AS package:

sudo wget http://swupdate.openvpn.org/as/openvpn-as-1.8.4-Ubuntu10.amd_64.deb

To install OpenVPN AS, enter the following command:

dpkg -i openvpn-as-1.8.4-Ubuntu10.amd_64.deb 

OpenVPN has created a default admin user called 'openvpn'. We need to set a password for 'openvpn'. To do that, enter the following command:

sudo passwd openvpn

You'll be prompted to enter your desired password. Make sure your password is secure. Administration and Client Software Setup OpenVPN AS web interfaces can be found at:
