1. Launch the server. This server does not require the powerful computing resources - you can choose a simple instance type.
2. Attach the elastic ip to the instance.

After launching, this VPN server is immediately fully operational. No server setup required.

To create a VPN connection, you will also need to install the OpenVPN client application on the client side. The OpenVPN client will require a configuration file (.ovpn), containing certificates. Such configuration files can be found in the folder "/home/admin/ovpn/" or can be downloaded from the server: https://ipaddress:8443/config/ovpn-download.php  Please use "config" as username and your instance ID as password to download these files with web browser.

Configuration files containing certificates are the same for all users. The certificates are automatically generated when the instance is first started. In addition to the mandatory configuration file (.ovpn), each user of the virtual network must have a username and password to establish the OpenVPN connection. User logins and passwords are stored in the database on the server, and users records can be managed with help of user management control panel: https://ipaddress:8443/daloradius/  Please use "administrator" as username and your instance ID as password.

Initially, the database of users contains 2 users: "user1" and "user2" so you can try to establish 2 simultaneous connections from 2 different computers to check the visibility of these computers through this OpenVPN server. Passwords for these users are automatically generated when the server is first started and can be found in the Web Panel (Management->List Users). According to initial settings in a Web Panel, the IP address 10.1.1.10 is assigned to "user1" and 10.1.1.20 is assigned to "user2" (initial local network: 10.1.1.0/24).

If clients "user1" and "user2" are simultaneously connected to this server at the same time, they will be able to see each other. You can check it with help of "ping" command: in Windows computers you can click "Run..." menu item of Start Menu, then print "cmd" to open Command Prompt and then execute command: "ping 10.1.1.20" (or "ping 10.1.1.10" on another computer respectively).

After successfully completing the ping test, you can establish the secure connection between remote computers via VPN. In Windows computers, you can click "Run..." menu item of Start Menu and execute the command like "\\10.1.1.20\" to create a network link to another computer.

It should also be noted that computer icons will also appear in the Windows network environment if the workgroup names of these client computers match.

In addition to the web control panel, you can also find the user credentials in the following ways:

• on linux welcome page (SSH, linux username: admin);
• via remote MySQL request (port 3306, username: remote, password is your instance ID, database: radius, table: radcheck). The database is readable and writable via 3306 port.

The IP address is reserved for each user and can be changed in the control panel.

To change network (for example, to 192.168.50.0/24) please run: "sudo bash /home/admin/set_network.sh 192.168.50.0"

By default the internet access is not allowed through the server. It can be set in config file: "/etc/openvpn3/443_tcp.conf"

OpenVPN ports: 443 (TCP)

If necessary, phpMyAdmin (webinterface for database management) is available at: https://ipaddress:8443/phpmyadmin/  Please use "administrator" as username and your instance ID as password. By default, access to phpMyAdmin is denied in file "/usr/share/phpmyadmin/.htaccess"

When used in a web browser protocol HTTPS, the browser will warn about the risk and you can accept it, since our task is to encrypt the traffic and not to doubt the authenticity of the certificate.

Linux username: admin
